For example, let’s find the volt-amps for a single-phase circuit with 20 amps of current at 120 volts.

Power_(VA) = 120 V × 20 A
Power_(VA) = 2,400 VA

So, a 120 volt circuit with 20 amps of current should have 2,400 volt-amps of apparent power.

Amps to volts calculation

The voltage V in volts (V) is equivalent to the power P in watts (W), partitioned by the ongoing I in amps (A):

V_(V) = P_(W) / I_(A)

The voltage V in volts (V) is equivalent to the current I in amps (A), times the opposition R in ohms (Ω):

V_(V) = I_(A) × R_(ω)

A "volt" is a unit of electric potential, otherwise called electromotive power, and addresses "the expected contrast between two places of a leading wire conveying a steady flow of 1 ampere, when the power scattered between these focuses is equivalent to 1 watt." Expressed another way, a capability of one volt shows up
