A 0.21-H inductor and a 88-Omega resistor are connected in series to a 220-V, 50-Hz AC source. The current in the circuit and the phase angle between the current and the source voltage are respectively. (Use pi= 22//7)

A transformer consisiting of 300 turns in the primary and 150 turns in the secondary gives output power of 2.2 kw. If the current in the secondary coil is 10 A, then the input voltage and current in the primary coil are:

A transformer consisting of 300 turns in the primary and 150 turns in the secondary gives output power of 2.2 kW.If the current in the secondary coil is 10 A, then the input voltage and current in the primary coil are :

In a series L-R circuit (L=35 mH and R=11 Omega) , a variable emf source (V=V_(0) sin omega t) of V_(rms)=220V and frequency 50 Hz is applied. Find the current amplitude in the circuit and phase of current with respect to voltage. Draw current-time graph on given graph (pi=22/7) .

An electric heater rated 2.2 kW, 220 V is operated for 2 h. Calculate : the safe limit of current which can pass through it,
