When a capacitor is connected to a battery:

An uncharged capacitor is connected to a battery. On charging the capacitor

Assertion: When an uncharged capacitor is connected across a battery, half the work done by the battery is stored as electric potential energy inside the capacitor and remaining half is dissipated in the form of heat. Reason: When an uncharged capacitor is connected across the battery then potential difference between the plates of capacitor increases from zero to the value of EMF of battery but battery supplies charge at the constant potential difference.

An unchanged capacitor is connected to a battery. On charging the capacitor (A) All the energy supplied is stored in the capacitor (B) half the energy supplied is dissipated in form if heat in connecting wire (D) the energy stored depends upon the time for which the capcitor is charged

If and uncharged capacitor is charged by connected it to a battery, then the amount of energy lost as heat is.

A capacitor of 5 muF is charged to a potential of 100 V . Now, this charged capacitor is connected to a battery of 100 V with the posiitive terminal of the battery connected to to the negative plate of the capacitor . For the given situation, mark the correct statement(s).

Assertion : When an uncharged capacitor is charged by a battery only 50% of the energy supplied is stored in the capacitor. Reason : Rest 50% is lost.

By evaluating int i^(2)Rdt ,show that when a capacitor is charged by connecting it to a battery through a resistor,the energy dissipated as heat equals the energy stored in the capacitor.

An Uncharged capacitor C is connected to a battery through a resistance R . Show that by the time the capacitor gets fully charged, the energy dissipated in R is the same as the energy stored in C .
