Three equal resistors connected in series across a source of e. m. f. together dissipate 10 watt of power. What would be the power dissipated if the same resistors are connected in parallel across the same source of e. m. f?
DIRECTIONS: The questions in this segment consists of two statements, one labelled as ?Assertion A? and the other labelled as "Reason R". You are to examine these two statements carefully and decide if the Assertion A and Reason R are individually true and if so, whether the reason is a correct explanation of the assertion. Select your answers to these items using codes given below. Assertion A: Air is an insulator. Reason (R): Those materials that do not allow electric current to pass through them are called insulators.
