Question

4) If a wire has resistance of 200 2 and the Current through it is 0.25 A
the potential difference across the wire must be.........
A) 400V B) 200V
C) 100V
D) 50V​

Answer 1

Given :-

• Resistence of wire = 200 Ω

• Current in wire = 0.25 A

To Find :-

• Potential difference across the wire

Solution :-

As we know

⇒ V = IR

⇒ V = 0.25 × 200

⇒ V = 50

∴ Potential difference across the wire is 50V
