Two voltmeters, V right or V left , each with an internal resistance of 10 6 Ω Ω are connected through wires of negligible resistance. The + side of both voltmeter is up as shown. A changing magnetic field is present in the shaded area. At a particular moment in time V right reads – 0.1V.
What is induced emf in the circuit at that moment?
Text Solution
Verified by ExpertsThe correct answer is:
B
Both voltmeter having equal internal resistance and they are in series, so both will have the same 0.1 volt drop across themselves.
∴ Induced emf must be 0.2 volt.
