The Ohm's Law Calculator will calculate the:
|The current flowing in a part of an electrical circuit (around a circuit component) is A [Amps]
|The current flowing in the main branch of a circuit is A [Amps]
|Current in the specific part of circuit calculation
|I = ∆V/R
I = /
|Current flowing in the main branch of circuit calculation
|Itot = ε/R + Rw + r
Itot = / + +
Itot = /
|Ohms Law Calculator Input Values
|Resistance of the circuit component (R) Ω [Ohm]
|Resistance of conducting wire (Rw) Ω [Ohm]
|Resistance of battery (r) Ω [Ohm]
|Potential difference across the circuit component (ΔV) V [Volt]
|Electromotive force of the source (ε) V [Volt]
Please note that the formula for each calculation along with detailed calculations are available below. As you enter the specific factors of each ohms law calculation, the Ohms Law Calculator will automatically calculate the results and update the Physics formula elements with each element of the ohms law calculation. You can then email or print this ohms law calculation as required for later use.
