How do you find the instantaneous value of voltage?

Let an instantaneous voltage v be represented by v = VM sin 2πft volts. This is a waveform which varies sinusoidally with time t, has a frequency f, and a maximum value, VM.

How do you find the instantaneous value of current?

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

What will be the instantaneous voltage for an AC supply of 230v and 50hz?

311.08 V
E =? = 311.08 V.

How is time related to the instantaneous voltage and current?

At a particular instant, the current is given by the time rate of change in the amount of charge. For a constant applied voltage (DC), the current is constant with respect to time since the charges move uniformly. But for AC circuits, the instantaneous current changes with time.

What is instantaneous voltage and current?

An instantaneous value of voltage or current is the induced voltage or current flowing at any instant during a cycle. The sine wave represents a series of these values.

What is the instantaneous value of a sine wave?

The sine wave represents a series of these values. The instantaneous value of the voltage varies from zero at 0° to maximum at 90°, back to zero at 180°, to maximum in the opposite direction at 270°, and to zero again at 360°. Any point on the sine wave is considered the instantaneous value of voltage.

What is the instantaneous value of a wave?

Instantaneous Value. This is the value (voltage or current) of a wave at any particular instant. often chosen to coincide with some other event. E.g. The instantaneous value of a sine wave one quarter of the way through the cycle will be equal to the peak value.

How do you calculate the maximum value of alternating current?

Maximum value of current, I max = 15A Frequency of alternating current, f = 60 Hz 1 The equation for instantaneous value of sinusoidal alternating current with θ as zero when time is zero, is given as I = I max sin 2π f t = 15 sin 2π 60 t

What is the instantaneous value of an AC sinusoidal current?

= 0.001936 seconds Ans. Example 2. An ac sinusoidal current has rms value of 40 A at 50 Hz frequency. Write expression of instantaneous current and obtain its value 0.002 sec after passing through maximum positive value. Expression for instantaneous value of an ac sinusoidal current with as zero when time is zero is given as

How do you find the average voltage of an alternating waveform?

To find the average voltage of an alternating wave form, one half cycle is divided into equally spaced ordinates. The instantaneous voltages at these mid-ordinates is calculated. By calculating the average value of these instantaneous voltage values, we get the average value of an AC waveform (whether voltage or current).
