A lamp draws 0329 A from a 115 V generator How much power do

A lamp draws 0.329 A from a 115 V generator. How much power does the generator deliver? Answer in units of W. How much energy does the lamp convert in 8.4 min? Answer in units of J.

Solution

003) Given that i=0.329A and V=115V

Hence power P=V*i

P= 115 * 0.329

P= 37.835W.

004) Electrical work or Energy W=V*i*t

where t is time

hence W= 37.835 * 8.4 * 60

So W= 19068.84J
