MHT CET 2025 Physics question
A coil of 'n' turns and resistance R is connected in series with a R resistance . The combination is moved for time 't' second through magnetic flux to . The induced current in the circuit is
Answer: (B)
Solution
The average induced emf in a coil of n turns is . The coil (resistance R) is in series with a resistance , so the total resistance is . Hence
