A
network contains linear resistors and ideal voltage sources. If values
of all the resistors are doubled, then the voltage across each resistor
is

A
network has two sources of different frequencies. The only method of
analysis which can be used to find current and voltages of different
branches is the use of

Open-circuit voltage is the potential difference between two point when the impedance between these points is

If H(s) is positive real, 1/H(s)

For a two- port reciprocal network, the output open circuit voltage divided by the input current is equal to

Norton's theorem reduces a two terminal network to

The phase difference between them is __________ degrees.
