Three sums of electrical power have been discussed. Here. This sum will give a basic idea of finding electrical power and electrical energy consumed by a load or electrical energy supplied by a source like a battery.
The sums are:
Two resisters of value 6 ohm and 12 ohms are connected in series across a battery of 12 volt. Draw the circuit diagram and calculate.
a) Current flowing through each resistor.
b) The electrical energy consumed by each resistor.
Sollution:

These two resistors again connected in parallel and the above data are again calculated.

Two bulb L1 and L2 of rating 100 W 200 V and 10 W 200 Volt respectively are connected across a supply of 200 V in series. Find
a) Current flowing through each bulb
b) which bulb will consume more power.
