What does it mean for a steady-state to be unstable (a.k.a, a source)? Explain..........

Give the expression for the time constant of a circuit consisting of an inductance with an initial current in series with a resistance R. To attain a long time constant, do we need large or small values for R? For L?

Q4.      The equation relating the current in a circuit with time is i=282.1 sin377t, where the current is measured in amperes and the time in seconds. Find the values of: The r.m.s current  The frequency  The instantenous value of the current when t=2.0ms

9. If the current through an ideal inductor is constant with time, what is the value of the voltage across the inductor? To what circuit element is an ideal inductor equivalent for circuits with constant currents and voltages?

Q1

for a resistance and capicitance in a series with a voltage source, show that it is possible to draw a phasor diagram for the current and all voltages from magnitude measurment of these quantities only .illustrate your answer graphically
