Answer 1

Total power supplied by battery is given by

P=VI
V= emf of battery =10V
I=current by battery =12mA

Answer 2

i don't get it

Answer 3

We need to find the total power of the circuit which is the total power expended by the battery which is given by

(emf of battery)*(total current supplied by the battery)

i showed before total current supplied by the battery is 12mA
and emf of battery is given to us as 10 V.

Answer 4

120 W?

Answer 5

120mW

Answer 6

as current is in mA

Answer 7

i thought power was measured in Watts
