Question

A bulb is connected to a battery of e.m.f. 8V. A steady current of 0.3A flows through the circuit. calculate total energy supplied by the battery in 10 minutes

Answer 1

Answer:P=VI

=8×0.3

=2.4J

Now,P=W/T

and W=E(energy)

So, we can write P=E/T

SO, PT=E

2.4×10min.=E

2.4×600sec.=E

1440Joule
