How do you calculate instantaneous AC current?
The instantaneous value of current in an AC circuit is i=2sin(100πt+π3)A. .

Voltage. So the RMS voltageMoreThe peak voltage is equal to the square root of 2 multiplied by the RMS. Voltage. So the RMS voltage is 120 volts and if we multiply that by the square root of 2.
What is the effective value of AC voltage?
The effective value of an alternating current is that current that will produce the same heating effect as an equivalent direct current. The effective value is called the root mean square (r.m.s.) value and whenever an alternating quantity is given, it is assumed to be the r.m.s. value.
What is instantaneous power in AC?
The instantaneous power is the power at a given instant. The average power is the power averaged over a cycle or number of cycles. The average ac current delivered to a circuit is zero.

A.C. Formula® II nutritionally supports the colon and intestinal tract to encourage a healthy digestive system. Pure Encapsulations A.C. Formula® II facilitates a thriving environment for microflora, an essential component of a healthy gut, within the colon and intestinal tract to promote a healthy digestive system.
How do you calculate AC current and voltage?
The average ac power is found by multiplying the rms values of current and voltage. Ohm’s law for the rms ac is found by dividing the rms voltage by the impedance. In an ac circuit, there is a phase angle between the source voltage and the current, which can be found by dividing the resistance by the impedance.
What is voltage in AC circuit?
The voltage over a resistive load in an AC system can be expressed as. U = R I (4) where. R = resistance (ohm) For a resistance load in an AC circuit the voltage is in phase with the current.
