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.
We hope you found the Ohms Law Calculator useful with your Physics revision, if you did, we kindly request that you rate this Physics calculator and, if you have time, share to your favourite social network. This allows us to allocate future resource and keep these Physics calculators and educational material free for all to use across the globe. We believe everyone should have free access to Physics educational material, by sharing you help us reach all Physics students and those interested in Physics across the globe.
The following Physics tutorials are provided within the Electrodynamics section of our Free Physics Tutorials. Each Electrodynamics tutorial includes detailed Electrodynamics formula and example of how to calculate and resolve specific Electrodynamics questions and problems. At the end of each Electrodynamics tutorial you will find Electrodynamics revision questions with a hidden answer that reveals when clicked. This allows you to learn about Electrodynamics and test your knowledge of Physics by answering the test questions on Electrodynamics.
