## Volts to amps calculation

The calculations for the current I in amps (A) is apparently equal to the value of power P in watts (W), which is divided by the value of voltage V in volts (V).

I(A) = P(W) / V(V)

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

I(A) = V(V) / R(Ω)

# How to convert volts to amps

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

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

### Volts to amps calculation with watts

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

I(A) = P(W) / V(V)

So

amp = watt / volt

or

A = W / V

#### For Example,

Find the value of current flow of an electrical circuit which has the power consumption of 40 watts with the voltage supply of 20 volts?

I = 40W / 20V = 2A

## Volts to amps calculation with ohms

The value of the current I which is measured in amps (A) is apparently equal to the value of voltage V measured in volts (V) and which is divided by the value of resistance R measured in ohms (Ω).

I(A) = V(V) / R(Ω)

So, the value is;

amp = volt / ohm

or it can be said that the value is,

A = V / Ω

#### For Example,

Find the value of current flow of an electrical circuit with the voltage supply of 40 volts and has the resistance of 10Ω?

According to ohm’s law the current I is equal to 30 volts divided by 10 ohms:

I = 40V / 10Ω = 4A
