Charging and Discharging of a Condenser

Charging and Discharging of a Condenser To study the charging of a condenser, to plot a graph of voltage (V) across it against time (t) and to determine the time constant from this graph. To plot a graph of charging current (i) against time (t) and to determine the time constant from this graph To study the discharging of a condenser, to plot a graph of voltage (V) across the condenser against time (t) and to determine the time constant from this graph To plot a graph of discharge current (i) against time (t) and to determine the time constant from this graph Features: The board consists of the following built-in parts: 0-20V D.C. at 25 mA, continuously variable regulated Power Supply Three SPDT switches Four electrolytic condensers Adequate no. of other electronic components Mains ON/OFF switch, Fuse and Jewel light The unit is operative on 230V ±10% at 50Hz A.C.
