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.
Conversion of heat into electrical energy may be achieved by using
If an electric iron draws a current of 4 A when connected to a 220 V mains, then its resistance must be
Inside a cell current flows from
Work done in moving an electric charge q in an electric field does not depend upon
DIRECTIONS: Read the passage (s) given below and answer the questions that follow. Passage -1 Those materials which do not allows electric current to pass through them are called insulators e.g., air, cork, rubber, thermocole, paper, etc. Insulators are used for covering electrical wires, plug tops, switches and other parts of electrical appliances. Air is an insulator of electricity because air have no-
The emf produced in a wire by its motion across a magnetic field does not depend upon
Select the correct statement:

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?
