Ohms law states that the current throw the conductor is directly proportional to the potential difference across its ends provided the temperature and other physical conditions are constant.

Where

V is Voltage measured in Volts,

V is Voltage measured in Volts,

I is the current flowing through the conductor in amperes,

R is the resistance measured in ohms.

Ohms law formula **(potential difference formula)** is used to find the Voltage, current and resistance in any given circuit, if any of the two quantities are given.

Below are some problems on ohms law which may be helpful for you. ### Solved Examples

**Question 1: **A potential difference of 10 V is applied across a conductor whose resistance is 25 $\omega$. Find the current flowing through it?

** Solution: **
**Question 2: **If current passing through the conductor is 5 A and conductance is 50 $\omega$. Find the potential difference?

** Solution: **

Given: Potential difference V = 10 V,

Resistance R = 25 $\omega$,

The current is given by I = $\frac{V}{R}$

= $\frac{10}{25}$

= 0.4 A.

Resistance R = 25 $\omega$,

The current is given by I = $\frac{V}{R}$

= $\frac{10}{25}$

= 0.4 A.

Current I = 5 A,

Resistance R = 50 $\omega$,

Potential difference V = IR

= 5A $\times$ 50 $\omega$

= 250 v.

Resistance R = 50 $\omega$,

Potential difference V = IR

= 5A $\times$ 50 $\omega$

= 250 v.
