Current Electricity and Electrical InstrumentHard
Question
By error, a student places moving - coil voltmeter V (nearly ideal) in series with the resistance in a circuit in order to read the current, as shown. The voltmeter reading will be
Options
A.0
B.4 V
C.6 V
D.12 V
Solution
I = 
= 0. if i = 0,
Potential difference is equal of EMF of cell. = 12 V
= 0. if i = 0,Potential difference is equal of EMF of cell. = 12 V
