Marks: +1, -0

Two lossy capacitors with equal capacitance values and power factors of 0.01 and 0.02 are in parallel, and the combination is supplied from a sinusoidal voltage source. The power factor of the combination is

0.03
0.015
0.01
0.0002

Validate

Solution:

P.F={P.F C_1+P.F_2C_2}/2

={0.01+0.02}/2=0.015
