1.
Two solenoids are coaxially placed. Solenoid 1: 500 turns, 30 cm long. Solenoid 2 (inside): 300 turns, same length. Area of cross-section = 2 $cm^{2}$. If current in solenoid 1 changes from 0 to 6 A in 0.02 s, the average induced EMF in solenoid 2 is: (μ_{0} = 4π × 10^{-7} H/m)
2.
The charge induced in a coil of resistance R and N turns when the flux through it changes by $\Delta$Φ is:
3.
A coil of self-inductance 2 H carries a current that changes from 5 A to 1 A in 0.1 s. The magnitude of average induced EMF and the change in energy stored are:
4.
The unit of rate of change of magnetic flux (dΦ/dt) is equivalent to:
5.
In the resonance curve shown, the bandwidth of the circuit is defined as the range of frequencies (f_{1} to f_{2}) at which the current falls to I_max/√2. The bandwidth is related to which circuit parameter?
