Question

A potential difference of 10 V is applied across a conductor whose resistance is 2.5 ohm. What is the value of current flowing through it? 

2 amperes

4 amperes

6 amperes

8 amperes

​

Answer 1

Given info : A potential difference of 10 V is applied across a conductor whose resistance is 2.5 ohm.

To find : the value of current flowing through it.

solution : using Ohm's law, V = IR

where V is potential difference and I is current and R is resistance.

here potential difference, V = 10 volts

resistance, R = 2.5 Ω

current, I = 10/2.5 = 4 Ampere.

Therefore the current through the conductor is 4 Ampere.
