Description : What happens to the angle between current and voltage, when a small capacitance is added in series with a highly inductive circuit? (A) Increases (B) Remains same as earlier angle (C) Decreases (D) Becomes indeterminant
Description : when voltage increases what happens to current ?
Last Answer : Decrease
Description : main function of the current regulator is A. To prevent the reversal flow of current from the battery when dynamo speed is drops. B. To safeguard against flow of high currents to battery when armature develops ... . C. To prevent building up of high voltage in a circuit. D. None of the above
Last Answer : B. To safeguard against flow of high currents to battery when armature develops more current.
Description : The output voltage of a battery drops from 100 V with zero load current to 80 V when load current is 2 A. The internal resistance of the battery is (a) 10 Ω (b) 20 Ω (c) 40 Ω (d) 50 Ω
Description : What happens to current flow in a capacitive circuit when the DC voltage across the capacitor is approximately equal to the source voltage?
Last Answer : Capacitor always charges up to the voltage of source. When the capacitor is charged to same as source voltage then there is no current flowing through the capacitor. The current through the capacitor is called displacement current.
