The frictional power (F.P.) is given by

A. F.P. = B.P. - I.P.

B. F.P. = I.P. - B.P.

C. $${\text{F}}{\text{.P}}{\text{.}} = \frac{{{\text{B}}{\text{.P}}{\text{.}}}}{{{\text{I}}{\text{.P}}{\text{.}}}}$$

D. $${\text{F}}{\text{.P}}{\text{.}} = \frac{{{\text{I}}{\text{.P}}{\text{.}}}}{{{\text{B}}{\text{.P}}{\text{.}}}}$$

Answer: Option B

Solution(By Examveda Team)

The frictional power (F.P.) is given by
F.P. = I.P. - B.P.
Friction power - It is defined as the how much power will be used for running the engine. Engine having some friction in gears, chain drives and shafts, matting parts. It consumes some energy from the power.
