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 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.

A current of 2 ampere flows through a resistance of 5Omega for 40 seconds, find the heat produced in calories :
