Q1PhysicsUnit 14: Electromagnetic Induction and Alternating Currents

The current flowing through the resistor in a series LCR a.c. circuit, is

\boldsymbol{I}=\varepsilon / \boldsymbol{R}

Now the inductor and capacitor are connected in parallel and joined in series with the resistor as shown in figure. The current in the circuit is now. (Symbols have their usual meaning)

Q2PhysicsUnit 14: Electromagnetic Induction and Alternating Currents

In series LCR circuit

R=18 \Omega

and impedance is

33 \Omega

. An r.m.s. voltage

220 V

is applied across the circuit. The true power consumed in a.c. circuit is

Q3PhysicsUnit 14: Electromagnetic Induction and Alternating Currents

A circuit consists of a resistor,an inductor and a capacitor connected in series. If the resistance of a resistor is

25 \Omega

and the value of inductive reactance is equal to capacitive reactance, then the net impedance of the circuit will be :
