Prove that in series combination of electrical appliances, the reciprocal of total power consumption is equal to the sum of the reciprocal of the powers of the individual appliances.

Prove that in parallel combination of electrical appliances, total power consumption is equal to the sum of the powers of the individual appliances.

Prove that in parallel combination of electrical appliances, total power consumption is equal to the sum of powers of the individual appliances.

Assertion: In parallel combination of electrical appliances, total power consum ption is equal to the sum of the powers of the indivisual appliances. Reason : Electrons move away from a region of lower potential to a region of higher potential.

Assertion: In parallel combination of electrical appliances, total power consum ption is equal to the sum of the powers of the indivisual appliances. Reason : Electrons move away from a region of lower potential to a region of higher potential.

Assertion: In parallel combination of electrical appliances, total power consum ption is equal to the sum of the powers of the indivisual appliances. Reason : Electrons move away from a region of lower potential to a region of higher potential.

Assertion : In parallel combination of electrical appliances, total power combination is equal to the sum of the powers of the individual appliances, Reason : In parallel combination , the voltage across each appliance is the same as required for the proper working of of eletrical appliance

(a) With the help of a suitable circuit diagram prove that the reciprocal of the equivalent resistance of a group of resistances joined in parallel is equal to the sum of the reciprocals of the individual resistances. (b) In an electric circuit two resistors of 12 Omega each are joined in parallel to a 6V battery. Find the current drawn from the battery.
