How Many Amps in 3981 Watts?

The answer to the question depends on:

  1. Whether you have a direct (DC) or alternating (AC) flow of electric charge
  2. In case of an AC single-phase system, the power factor (PF)
  3. In case of an AC three-phase system the PF as well as a constant for line to line voltage L-L(V) or line to neutral voltage L-0(V)

In an alternating current circuit, the power factor (PF) is the quotient of real power / apparent power with a value in between 0 and 1: 0 ≤ PF ≤ 1.

In the International System of Units (SI):

  • The ampere (A) aka “amp” is the unit of electric current
  • The volt (V) is the unit of electric potential
  • The watt (W) is the unit of power
  • The ohm (Ω) is the unit of electrical resistance

Next, we explain the math:

How to Convert 3981 Watts to Amps?

  • DC: I(A) = 3981 W / V(V)
  • AC, Single Phase: I(A) = 3981 W / (PF × V(V))
  • AC, Three Phase, Line to Line Voltage: I(A) = 3981 W / (√3 × PF × VL-L(V))
  • AC, Three Phase, Line to Neutral Voltage: I(A) = 3981 W / (3 × PF × VL-0(V))

  • Similar calculations include, for example:
