Basics Of Circuit

A simple electric circuit has a 24V battery and a resistor of 60 ohms. What will be the current in the circuit? The resistance of the connecting wires is negligible.

In the circuit shown in figure find a) the rate of conversion of internal (chemical) energy to electrical energy within the battery (b) the rate of dissipation of electrical energy in the battery (c) the rate of dissipation of electrical energy in the external resistor.

Is work dome by a battery always equal to the thermal energy develop in electrical circuits? What happens if a capacitor is connected in the circuit?

For driving a current of 3 A for 5 minutes is an electric circuit, 900 J of work is to be done. Find the emf of the source in the circuit.

A certain electric circuit with a resistance R is supplied power simultaneously from n identical storage batteries. For what internal resistance of the storage batteries will the current in the circuit be the same when they are connected in series and in parallel ?
