The line A to neutral voltage is 10∠15°V for a balanced three phase star-connected load with phase sequence ABC. The voltage of line B with respect to line C is given by

A system transfer function is $H\left(s\right)=\frac{a_1{s}^2+b_{1}s+c_1}{a_2{s}^2+b_{2}s+c_2}$. If a₁ = b₁ = 0, and all other coefficients are positive, the transfer function represents a

The power supplied by the 25 V source in the figure shown below is ________ W.

The switch SW shown in the circuit is kept at position ‘1’ for a long duration. At t = 0+, the switch is moved to position ‘2’ Assuming |V₀₂| > |V₀₁|, the voltage V${}_C$ (t) across capacitor is

In a linear two – port network, when 10 V is applied to Port 1, a current of 4 A flows through Port 2 when it is short-circuited. When 5 V is applied to Port, a current of 1.25 A flows through a 1 Ω resistance connected across Port 2. When 3 V is applied to Port 1, then current (in Ampere) through a 2 Ω resistance connected across Port 2 is __________.
