Explanation:
The watts that are consumed in a circuit that is having power factor of 0.2 and input is 100V at 4 ampheres is 80 watts.
Given that power factor is 0.2, input is 100V and electricity current be 4 amperes.
We are required to find the number of watts that are consumed in circuit.
An electric current is basically a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space.
Power factor is basically the ratio of working power, measured in kilowatts , to apparent power, measured in kilovolt amperes.
Number of watts that are consumed will be=100*0.2*4
=80 watts
Hence the watts that are consumed in a circuit that is having power factor of 0.2 and input is 100V at 4 ampheres is 80 watts.
