. Two resistive loads A& B of ratings 100V, 10W and 100V, 2.5W respectively are connected in series across a
constant voltage supply of 100V. A voltmeter having an internal resistance of 12kΩ is connected across B. Calculate
the voltage across B before and after voltmeter was connected. Also, find the change in supply current when
voltmeter is connected.
