The work done in placing a charge of 8uC on a condensor of capicity 100 nF is_

Explanation

The work done in placing a charge of 8 microcoulombs (μC) on a capacitor of capacitance 100 nanofarads (nF) is 3.2×10-4J .A microcoulomb is a very small unit of charge, equal to one millionth of a coulomb. A nanofarad is also a very small unit of capacitance, equal to one billionth of a farad. A farad is the unit of capacitance in the International System of Units (SI).The work done in charging a capacitor is equal to the energy stored in the capacitor. The energy stored in a capacitor is proportional to the square of the charge on the capacitor. In this case, the charge on the capacitor is 8 μC, so the energy stored in the capacitor is 3.2×10-4J .
