Volts to amps calculation

Volts to amps calculation with watts

So 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)

Example 1

What is the current flow of an electrical circuit that has power consumption of 45 watts and voltage supply of 25 volts?

I = 45W / 25V = 1.8A

Example 2

What is the current flow of an electrical circuit that has power consumption of 55 watts and voltage supply of 25 volts?

I = 55W / 25V = 2.2A

Example 3

What is the current flow of an electrical circuit that has power consumption of 90 watts and voltage supply of 15 volts?

I = 90W / 15V = 6A

Volts to amps calculation with ohms

So 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)

Example 1

What is the current flow of an electrical circuit that has voltage supply of 20 volts and resistance of 10Ω?

According to ohm's law the current I is equal to 20 volts divided by 10 ohms:

I = 20V / 10Ω = 2A

Example 2

What is the current flow of an electrical circuit that has voltage supply of 40 volts and resistance of 10Ω?

According to ohm's law the current I is equal to 20 volts divided by 10 ohms:

I = 20V / 10Ω = 4A

Example 3

What is the current flow of an electrical circuit that has voltage supply of 30 volts and resistance of 20Ω?

According to ohm's law the current I is equal to 30 volts divided by 20 ohms:

I = 30V / 20Ω = 1.5A
