MHT CET 2025 Physics question
A coil having 'N' turns and resistance 'R' is connected to a galvanometer of resistance '6R' . The magnetic flux linked with this coil changes from weber to weber in time 't' second. The induced current in the circuit is.
Answer: (B)
Solution
Induced e.m.f. (magnitude): . The coil (resistance ) and galvanometer (resistance ) are in series, so the total resistance is . Induced
