A direct current of 2 A and an alternating current having a maximum value of 2 A flow through two identical resistances. The ratio of heat produced in the two resistances will be

A steady current of magnitude I and an AC current of peak value I are allowed to pass through identical resistors for the same time. The ratio of heat produced in the two resistors will be

A direct current of 2A and an AC of peak value 2A flows through resistances 2Omega and 1Omega respectively. Find the ratio of heat produced in the two resistances in same interval.

If alternating current of rms value ‘a’ flows through resistance R then power loss in resistance is-

A current of 2A flows through a 12 V bulb then find resistance.

If a current of strength 3 A flows through a resistance of 20 Omega for 10 minutes, then calculate the amount of heat produced in the resistance.
