## Ohm’s law

Ohm’s law

The most crucial factor in analyzing a current is to consider the relationship between voltage and current, where the use examines a resistance, which creates a connection between current and voltage. A resistor prohibits the flow of electrons where sometimes the amount of current flowing to a particular component can be reduced as well as the energy moving to sensitive particles. The paper discusses the ohm’s law and its application.

OHM’s law determines the features and characteristics of a circuit by determining how current flows and the amount of resistance in the course. Voltage is calculated by multiplying resistance and voltage (V=IR). Where the relationship between the three is that the current is equal to voltage divided by resistance.

Voltage is an electric potential running through a current, which is potential energy per unit charge considered as joules, and the unit for voltage is volts Current flows at a specific amount of time where current is the amount of time per unit time. The amount of charge flowing to a component where the current flowing lowers due to the application of resistance. The amount of charge flowing impeded is known as the ohms.

Having the voltage and resistance, one could calculate the current through a particular circuit where the ohm’s law is applied by the use of dividing voltage over the opposition. Ohms is a type of modern physics formulas that states that current flowing through a conductor is directly proportional to the potential difference applied across its ends, provided temperature and other physical conditions remain unchanged. Temperature is kept constant because resistance value affects the amount of resistance; therefore, keeping constant temperature resistance will be considered consistent.

Voltage = current x resistance, or volts = amps x ohms, or V = A x Ω.

Ohm’s law has many applications, for instance, applied in an electronic circuit, convectional domestic fan regulator, voltage divider circuit, and many more.

Ohms law is used in convectional fans using a potentiometer as the resistance where the circular knob in the fan rotates to achieve resilience. The resistance is used to calculate the energy and current flowing through the circuit, therefore, completing the ohms law. Another application is the dc ammeter, as well as dc measuring items, which are used to change the flow of currents.

Electronic devices such as phones and laptops consist of a battery with volts of 0.7 to 1 and a resistor to control the amount of current flowing through the apparatus. The ohms law, therefore, calculates the amount of current flowing in the device, for instance, a phone needs 0.8 volts using 6 volts through it. Find the resistance, which is voltage divided by current R=V/I. Electronic devices use various resistors that are chosen for each item exclusively, for instance, television, iron box, and such things. The ohms law is applied in sizing the resistor through the formulae.

Ohms law is not only used in domestic appliances such as kettles but also used by massive machines such as rockets and airplanes. Fuses are used to limit the amount of energy flowing through a circuit as well as maintain a certain. Fuses are used by more than one device, and through the knowledge ohms law is used to decide or choose the resistors needed for specific tools as well as the importance of using resistances.

Electric heaters are mostly used in cold seasons, such as winter. Electric heaters consist of a metal coil that is compressed and has a high resistance to allow a certain amount of current flowing through them. The amount of current permitted determines the required heat, and the power needed to perform the heated process is determined and calculated by the use of ohms law.

Aircraft and rockets are protected from lightening by the use of various resistors. For instance, the components of the helicopter are mounted on the outer part where the lightning strikes directly. The vulnerable zones or rather the good conductors are identified and installed to prevent the lightning currents from penetrating through into the system. For instance, some of the external components mounted include the antennas, control surface sensors, and many others, which are protected by the use of different resistance. The antennae are installed by the use of gas surge arrestors, while the use of diode clamps protects the control surface sensors.

Aircrafts cables are all coupled to lightning, for instance, inductive coupling cables to protect the hardware from lightning, cross-coupling to exposed wires, inductive coupling, for, example the windows and doors as well as IR voltage across the airframes and the induced cable currents. Application in an electric circuit makes the circulation of energy or instead power simpler. Ohms law is used by electricians and electrical engineering students to validate the static value of the circuit device, the current levels as well as voltage dropping and supply.

Test instruments are used to detect the number of amperes if the current is higher than the optimum range; therefore means that resistance level has reduced or the volts have increased, which is an issue. Most of the time, when the volts are too high, especially in electronic devices, the device heats up, and temperatures rise, which consequently leads to damaging the equipment. Sometimes lower currents mean that the resistance level has increased therefore reducing the volts. In such cases, electricians check on the connection where probably the appliance is poorly connected, damaged, or corroded. Technicians use the ohms law to detect problems related to current flow by use of the basic science of circuit, which includes the protons, neutrons, and electrons.

Resistors can be connected in a series, also known as a series of resistors. A series of resistors means there is only one path for current to flow; therefore, the law of series of resistance sates that individual voltage throughout the circuit is equal to the total energy. Current passing through the channel is the same in every point of the component, and different resistances similar to the total circuit resistance. Resistors also applied in the parallel circuit where, in most cases, parallel circuits are used to equalize voltage from every part of the network.

The law of parallel circuit states that voltage is the same at every point as well as individual current accumulates to the total current running through the channel. Ohms law is not applicable in two instances; one, in networks that allow the flow of current in one direction, the systems are known as the unilateral networks, for, example the transistors. More so, ohms law is inapplicable to elements with no proportionality of currents and voltage, For instance, the linear elements where resistance value do not remain constant but changes due to different amount of current and voltage, for example, the thyristor.

Ohms law is fundamental and easy to apply in physics, which is used in calculating or measuring the level of voltage current and resistance in an electric circuit or instead in any compliance. The ohms law applies the relationship between the current, voltage, and strength, where resistance is used to reduce the current flow and volts per unit charge. Ohms is involved in various fields as well as in household appliances, for instance, the electric heater, mobile phones, and chargers, iron boxes, and kettles, as well as in electrical circuits. Ohms laws are applied in larger machines such as the aircraft, which protects the system from a lightning strike by the use of resistors.
