Ohms Law Formula

Ohms law says that the current running through the conductor is directly proportional to the potential difference across its extremities as long as the temperature and other physical conditions are constant.

Formula of Ohm’s Law

Ohms law formula is articulated as

V=IR

Where
Voltage is V and is measured in Volts,

The current flowing through the conductor is I and it represented in amperes,

the resistance is R and is measured in ohms

Ohm’s law formula (potential difference formula) is made use of to calculate the Resistance, Current, and Voltage in any given circuit if any of the two quantities are given.

Ohm’s Law Solved Examples

Underneath are some numerical on Ohm’s law which might be useful for you.

Problem 1: A potential difference of 10 V is applied across a conductor whose resistance is 25 ω. Calculate the current flowing through it?
Answer:

Given: Potential difference V = 10 V,
Resistance R = 25 ω,

V=I/R

V=10/25

V=0.4volts

Problem  2: If a conductor resistance is 50 Ω and the current passing through the is 5 A. Calculate the potential difference?
Answer:

Current I = 5 A,
Resistance R = 50 ω,
Potential difference V = IR
= 5× 50
V = 250 volts
