If the input frequency is 50 Hz, the output frequency of a full wave rectifier is:
A full-wave rectifier inverts every half-cycle of the AC input signal, effectively doubling the frequency of the input AC signal.
Therefore, if the input frequency is 50 Hz, the output frequency of a full-wave rectifier will be: \[ 2 \times 50 \, {Hz} = 100 \, {Hz} \]
Acceleration-time (\(a-t\)) graph of a body is shown. The corresponding velocity-time (\(v-t\)) graph is
