A nonideal battery is connected to a resistor. Is work done by thr battery equal to the hermal energy developed in the resistor?Does your answer change If the battery is ideal?

Two nonideal batteries are connected in parallel. Consider the following statements:

A battery is used to charge a parallel plate capacitor till the potential difference between the plates become equal to the electromotive force of the battery. The ratio of the energy stored in the capacitor and the work clone by the battery will be .......

When a 12V battery is connected across an unknown resistor, there is a current of 2.5 mA in the circuit. Find the value of the resistance of the resistor.

A battery lights a bulb. Describe the energy changes involved in the process.

A 12pF capacitor is connected to a 50V battery. How much electrostatic energy is stored in the capacitor?

(a) Three resistors 2 Omega 4 Omega and 5 Omega are combined in parallel. What is the total resistance of the combination ? (b) If the combination is connected to a bettery of emf 20 V and neglibible internal resistance, determine the current through each resistor, and the total current drawn from the battery.

A capacitor has some dielectric between its plates and the capacitor is connected to a DC source. The battery is now disconnected and then the dielectric is removed. State whether the capacitance, the energy stored in it, electric field, charge stored and the voltage will increase, decrease or remain constant.
