8 to 032): In the following
Assertion and Reason have been
at the statements carefully and
et alternative from the following
ceil acts as a positive terminal
31. Assertion: The statement of Ohm's law
is V IR
Reason: V = IR is the equation which
defines resistance.
32. Assertion: Bending of wire decrease the
resistance of electric wire.
Reason: The resistance of a conductor
depends on length, thickness, nature of
material and temperature of the conductor
