A lamp is connected in series with a capacitor. Predict your observations for de and ac connections.

Why is an ammeter connected in a series?

A capacitor and resistor are connected in series with an ac source. If the potential difference across C and R are 120 V and 90V respectively and if the rms current of the circuit is 3A, calculate (i) impedance and (ii) power factor of the circuit.

A capacitor of 20 µF and charged to 500 V is connected in parallel with another capacitor of 10µF charged to 200V. Find the common potential.

An inductor of self inductance L = 50 mH is connected in series with a non inductive resistor of resistance R = 10Omega . A source of e.m.f epsilon= (100sin 50 pit) Volt is connected in the circuit. Find the impedance of the circuit
