6 Examples Of Ohm’s Law In Everyday Life
Ohm’s Law is the relationship between the current, voltage and resistance and which is derived by the German Physicist, George Simon Ohm. Ohm law’s application ranges from household appliances like heaters to the high tension wires and massive projects like rockets and spaceships.

“Ohm law states that at a constant temperature, the current (I) flowing through the resistor is directly proportional to the voltage or potential difference (V) applied across the resistor”.
The constant of proportionality is written as R and this is the resistance value of the resistor
Let’s learn about its applications in our daily life activities.
1. Conventional Domestic Fans
We can control the speed of the fans at our homes by moving the regulator to and fro. Here the current flowing through the fan is controlled by regulating the resistance through the regulator. A circular knob on the component can be rotated to achieve a variable resistance on the output terminals. For any specific value of the input, we can calculate the resistance, current and thus power flowing through Ohm’s Law.
2. Electric Heaters
The electric heaters are the common appliances used in winters throughout the world. The heaters have a metal coil which has high resistance that permits a certain amount of current to flow through them to provide the required heat. Also, the power to be supplied to the heaters is calculated using this law.
