A DC voltage of 100 V is applied to a coil having R = 10 ohm and L = 10 H. What is the time constant of the circuit?

The below circuit shows a s-phase system having a balanced self-inductive reactance of X_L per phase a mutual reactance of X_m between pairs of phases. The line currents are I_a, I_b and I_c and they may be unbalanced.

The series voltage-drop relations would be

V_aa′  = I_a X_L + I_b X_m + I_c X_m

V_bb′  = I_a X_m + I_bX_L + I_cX_m

V_cc′ = I_a X_m + I_b X_m + I_C I_L

The positive, negative, and zero-sequence reactance X₁, X₂ and X₀, respectively = would be

In the given circuit, for maximum power to be delivered to R_L, its value should be __________ Ω. (Round off to 2 decimal places.)

A 10 V battery having 1Ω internal resistance is connected to non-linear load having relation

7i = V² + 2V.

Value of ‘i’ is _______ amp.

A three-phase balanced voltage is applied to the load shown. The phase sequence is RYB. The ratio is _______.

If the current following through an inductor of inductance L is (2t² + t). then the power is.
