Question # 1
What relation between the voltage through inductor V L and voltage through resistor V R is represented by the phasor diagram, as shown in image?
Question # 2
When a choke coil is placed in series with an electric lamp in an A.C circuit, Why it causes the lamp to become dim?
Question # 3
A student connects a long air core coil of manganin wire to 100 V DC source and records a current of 1.5A. When the same coil is connected across a 100 V, 50 Hz AC source, why the current reduces to 1A?
Question # 4
A capacitor of capacitance 79.5 μ F is connected in series with a resistance of 30 Ω across a 100 V, 50 Hz supply. What is the impedance and phase angle?
Question # 5
When a long air core coil of manganin is connected to a 120 V DC source, a current of 2A is recorded, and when same coil is connected across 120 V, 50 Hz AC supply, current is reduced to 1 A. What is the reactance of coil?
