In a circuit, the current lags behind the voltage by a phase difference of π/ 2, the circuit will contains which of the following ?

A choke is preferred to a resistance for limiting current in AC circuit, because

In L-C-R circuit if resistance increases, quality factor

In an L-C-R series AC circuit, the voltage across each of the components L, C and R is 50 V. The voltage across the L-C combination will be

In an L-C-R circuit, capacitance is changed from C to 2C. For the resonant frequency to remain unchanged, the inductance should be changed from L to

In an AC circuit, the current lags behind the voltage by π/3. The components of the circuit are

An inductance 1 H is connected in series with an AC source of 220 V and 50 Hz. The inductive reactance (in ohm) is

The current voltage relation of diode is given by I = (e^l000V/T – 1) mA, where the applied voltage V is in volt and the temperature T is in kelvin. If a student makes an error measuring ± 0.01 V while measuring the current of 5 mA at 300 K, what will be the error in the value of current in mA?
