How do you calculate apparent power from voltage and current?

  1. The difference between VA and Watts.
  2. Apparent power, which is the product of rms (root mean square) volts.
  3. Real power, which is the time average of the instantaneous product of.
  4. Reactive power, which is the time average of the instantaneous product.
  5. P = V x A = VA.
  6. P = 120 V x 6 A = 720 Watts.

What is the formula to calculate the reactive power?

Reactive power: Q = V x Ir (kvar)

How do you calculate the power factor of an RL circuit?

  1. Calculate Power factor (pf) p.f. = cos (14º) p.f. = 0.097.
  2. Calculate Applied Voltage, V. V = I Z. Z = √R2 + XL2 so, V = I√R2 + XL2
  3. Calculate True Power, P. P = EI cos θ P = (412.3)(2)(0.97) P = 799.86 watts.
  4. Calculate Reactive Power, Q. Q = EI sin θ Q = (412.3)(2)(0.242)
  5. Calculate Apparent Power, S. S = EI. S = (412.3)(2)

How is apparent power calculated for an AC circuit?

Apparent Power is the Total Power Flowing The total power flowing is known as the “apparent power” and is measured as the product of the voltage and current (V * I).. For example, if 208 volts and 5 amps are measured – the apparent power is 1040VA (VA means volt-amps – the measurement unit of apparent power).

How do you calculate power in an AC circuit?

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.

How do you calculate electrical variables?

Electrical voltage V(V) in volts is equal to the 1000 times of reactive power Q(kVAR) in kilovolt amp reactive divided by the reactive current I(A) in amps. In other words, Voltage is equal to VAR divided by the reactive current. Voltage is equal to 10,00,000 times of MVAR divided by the reactive current in amps.

How do you calculate the power factor of an RLC circuit?

⇒XC=1ωC where C is the capacitance and XL=ωL where L is the inductance. ⇒ω=2πf where f is the frequency of AC source. Power factor is also the ratio of resistance of LCR circuit to its impedance. The power factor of an LCR circuit is the ratio of the resistance to the total impedance of the circuit.
