railway RRB Technician Grade 1 Mock Test 2024 Electrical and Electronics Measurements Indicating Instruments PMMC Instrument
In a PMMC instrument, the final steady state deflection is:
1
∝ i, where i is the current through the coil
2
∝ 1 / i, where i is the current through the coil
3
∝ i2, where i is the current through the coil
4
∝ 1 / i2, where I is the current through the coil
