Question

In transferring 1.5 C charge through a wire, 9 J of work is done. Find the potential difference across the wire.

WhatsApp

Answer

charge (q) = 1.5 C

work = 9 J

potential difference across the wire

V = w/q

Substituting the values in the formula, we get,

V = 9/1.5 = 6 V

Hence, the potential difference across the wire = 6 V.
