In which direction currrent flows in a circuit ?

A current through a wire PQ is increasing. In which direction the induced current flows in the closed loop?

Consider a magnet surrounded by a wire with an on/off switch S (Fig. EP 6.11). If the switch is thrown from the off position (open circuit) to the on position (closed circuit), will a current flow in the circuit? Explain.

A 60muF capacitor, a 0.3H inductor and a 50Omega resistor are connected in series with a 120V-60Hz a.c. source. Calculate the impedance of the circuit and current flowing in the circuit.

Give the direction in which the induced current flows in the coil mounted on an insulated stand, when a bar magnet is quickly moved along the axis of the coil from one side to the other as shown in the figure.

When does the current flow in an electric circuit?

When a capacitor is connected in series LR circuit the alternating current flowing in the circuit increases. Explain why.

When a circuit element X is conneted across a.c. sourceof emf 220sqrt2V , a current sqrt2 A flows through it and this current is in phase with applied voltage. When another element Y is connected across same a.c. source, the same current flows in the circuit, but it leads the voltages by pi//2. Find current that flows in the circuit when series combination of X and Y is connected acorss same a.c. voltage.
