### Amps to volts calculation

##### Amps to volts calculation with watts

So The voltage V in volts (V) is equal to the power P in watts (W), divided by the current I in amps (A).

V(V) = P(W) / I(A)

#### Example 1

What is the voltage supply of an electrical circuit that has power consumption of 55 watts and current flow of 3 amps?

The voltage V is equal to 55 watts divided by 3 amps:

V = 55W / 3A = 18.333V

#### Example 2

What is the voltage supply of an electrical circuit that has power consumption of 65 watts and current flow of 3 amps?

The voltage V is equal to 65 watts divided by 3 amps:

V = 65W / 3A = 21.666666667V

#### Example 3

What is the voltage supply of an electrical circuit that has power consumption of 95 watts and current flow of 3 amps?

The voltage V is equal to 95 watts divided by 3 amps:

V = 95W / 3A = 31.666666667V

##### Amps to volts calculation with ohms

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

V(V) = I(A) × R(Ω)

#### Example 1

What is the voltage supply of an electrical circuit that has current flow of 3 amps and resistance of 20 ohms?

According to ohm's law the voltage V is equal to 3 amps times 20 ohms:

V = 3A × 20Ω = 60V

#### Example 2

What is the voltage supply of an electrical circuit that has current flow of 3 amps and resistance of 30 ohms?

According to ohm's law the voltage V is equal to 3 amps times 30 ohms:

V = 3A × 30Ω = 90V

#### Example 3

What is the voltage supply of an electrical circuit that has current flow of 3 amps and resistance of 50 ohms?

According to ohm's law the voltage V is equal to 3 amps times 50 ohms:

V = 3A × 50Ω = 150V
