When the instantaneous applied voltage across a capacitor is zero the instantaneous current through the capacitor will be?

When the instantaneous applied voltage across a capacitor is zero the instantaneous current through the capacitor will be?

At the exact moment when the voltage across the capacitor is greatest, the voltage is neither rising nor falling. Therefore, the instantaneous current must be zero at this instant.

When voltage is maximum what is zero?

For a pure inductive circuit, voltage leads the current by 90°. So, the instantaneous current is zero when the instantaneous voltage is maximum.

How do you find instantaneous current in an AC circuit?

The instantaneous value of current in an AC circuit is i = 2sin ( 100pit + pi/3 ) A.

What is instantaneous current in AC?

The instantaneous value of current in an AC circuit is i=2sin(100πt+π3)A. Hint: Instantaneous current is the amount of charge passing through a conductor at a moment of time, whereas the time-averaged current is the total amount of charge passing through a conductor in a time interval.

What is the current in an inductive circuit when the applied voltage is maximum?

What is the current in an inductive circuit when the applied voltage is maximum? Explanation: The current in an inductive circuit is zero or minimum when the value of the applied voltage is maximum. 6.

What is the current in LCR circuit?

When a constant voltage source or battery is connected across a resistor, current is developed in it. The magnitude of current remains constant as well. If the direction of current through this resistor changes periodically or alternately, then the current is called alternating current.

How do you find the instantaneous value?

The instantaneous values of a sinusoidal waveform is given as the “Instantaneous value = Maximum value x sin θ ” and this is generalized by the formula. Where, Vmax is the maximum voltage induced in the coil and θ = ωt, is the rotational angle of the coil with respect to time.

What is instantaneous current and RMS current?

Instantaneous current (i) the value of current at a certain instant in time. RMS current (I) is the DC-equivalent current that would cause the same power dissipation in a resistor.

Why is current instantaneous?

Current is constituted by the flow of charges. Instantaneous current is given by the amount of charge passing through a conductor at any given instant of time.
