Voltmeters V 1 and V 2 are connected in series across a D.C. line. V 1 reads 80 volts and has a per volt resistance of 200 ohms. V 2 has a total resistance of 32 kilo ohms. The line voltage is
Text Solution
Verified by ExpertsThe correct answer is:
D
Current flowing through 
= Current flowing through 
= 
.
So, potential differences across 
is
Hence, line voltage
