2.  In an unloaded transformer, the fluxes limiting the primary and secondary are 30 mWb and 20 mWb. The coefficient of coupling is 

Your Answer: Option (Not Answered) Correct Answer: Option D Explanation: Φ_{11} = (1  k) Φ_{1} φ_{11} = φ_{1}  φ_{2} 30  20 10 mWb 10 mWb = (1  k) 30m 0.33 = 1  k k = 0.67 . Learn more problems on : Networks Analysis and Synthesis Discuss about this problem : Discuss in Forum 
3.  In following circuit, steady state is reached with S open, S is closed at t = 0, the current I at t = 0^{+} is given by 

Your Answer: Option (Not Answered) Correct Answer: Option C Explanation: When steady state is reached with s open, capacitor will act as open circuit Current in 4Ω resistor will be = 6A at steady state. Voltage across 4Ω = 6 x 4 24 volt. Current in 2Ω resistor due to 6A 3A current due to 16 V, source. I = 16/2 8A, this current divide in (2 + 2) Ω is 4Ω resistor current in 2Ω resistor 4A + 3A 7A.
