How to convert amps to volts

How to convert electric current in amps (A) to voltage in volts (V).

You can calculate volts from amps and watts or ohms, but you can't convert amps to volts since volt and amp units represent different quantities.

Amps to volts calculation with watts

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)

So

volt = watt / amp

or

V = W / A

Example 1

What is the voltage supply of an electrical circuit that has power consumption of 45 watts and current flow of 4 amps?

The voltage V is equal to 45 watts divided by 4 amps:

V = 45W / 4A = 11.25V

Example 2

What is the voltage supply of an electrical circuit that has power consumption of 55 watts and current flow of 4 amps?

The voltage V is equal to 55 watts divided by 4 amps:

V = 55W / 4A = 13.75V

Example 3

What is the voltage supply of an electrical circuit that has power consumption of 100 watts and current flow of 4 amps?

The voltage V is equal to 100 watts divided by 4 amps:

V = 100W / 4A = 25V

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)

So

volt = amp × ohm

or

V = A × Ω

Example 1

What is the voltage supply of an electrical circuit that has current flow of 5 amps and resistance of 10 ohms?

According to ohm's law the voltage V is equal to 5 amps times 10 ohms:

V = 5A × 10Ω = 50V

Example 2

What is the voltage supply of an electrical circuit that has current flow of 6 amps and resistance of 10 ohms?

According to ohm's law the voltage V is equal to 6 amps times 10 ohms:

V = 6A × 10Ω = 60V

Example 3

What is the voltage supply of an electrical circuit that has current flow of 5 amps and resistance of 15 ohms?

According to ohm's law the voltage V is equal to 5 amps times 15 ohms:

V = 5A × 15Ω = 75V

FAQ

How many volts is in a amp?

ane ampere
Volt - The unit of measurement of the electric force or pressure that causes an electric current to flow in a circuit. One volt is the amount of pressure required to flow one ampere of current against an ohm resistance.

What is 50 amps in volts?

A 50 amp plug has four prongs -- two 120 volt hot wires, a neutral wire and a ground wire -- that supply two separate 50 amp, 120 volt feeds.

How do you calculate voltage from amps?

P = V x I. Here P is the power in watts. V is the voltage in volts. I is the current in amps.

How do you convert amps to volt amps?

VA calculation formula for 3 phase amps

1. S(VA) = √3 × I(A) × VL-L(V) So volt-amps are equal to the square root of 3 times amps times volts:
2. Kilovolt-amps = √3 × amps × volts. OR.
3. kVA = √3 × A V. Example. ,
