Experimental Training Board has been specifically designed to study Charging and Discharging of a Condenser.
Practical experience on this board carries great educative value for Science and Engineering Students.

Object:
 

01. 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.
02. To plot a graph of charging current (i) against time (t) and to determine the time constant from this graph.
03. 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.
04. To plot a graph of discharge current (i) against time (t) and to determine the time constant from this graph.
