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 hollow metallic sphere of radius r is kept at potential of 1 Volt. The total electric flux coming out of the concentric spherical surface of radius R (> r) is

The driving point impedance Z(s) for the circuit shown below is

A signal is represented by

x≤ft( t ) = ≤ft\{ {*20c 1&≤ft| t |& < 1\\ 0&≤ft| t |& > 1 } .

The Fourier transform of the convolved signal y(t) = x(2t) * x(t/2) is

For the signal f(t) = 3 sin 8πt + 6 sin 12πt + sin 14πt, the minimum sampling frequency (in Hz) satisfying the Nyquist criterion is -----------.
