## Resistance (R) calculator tool introduction

Hello friends, welcome to our website education tool, with the help of this tool, you can find the resistance of any circuit. Just you should have some data already known such as voltage (v), and current (i) and if you do not have this information then you should find it first. If you will have information about Watt ie Power (w) instead of this information, then you can find out the resistance of any circuit with the help of this tool.

## What is Ohm's law?

Ohm's law is used to determine the relationship between voltage, current, and resistance in an electrical circuit.

V = I x R.

V = Volatge

I = Current (amp)

R = Resistance (Ω)

When stated explicitly, it means that voltage = current x resistance, or volts = amps x ohms, or V = A x Ω.

In an electrical circuit, we can calculate the total resistance of the circuit, or the resistance of each receiver within the circuit, through ohm's law: R = V/I; V in volts and I in amps will give us the resistance in Ohms (Ω).

## What does resistance do in Ohm's law?

Electric resistance. Resistance is the opposition presented by bodies to the passage of electric current. It is measured in ohms [W]. The opposition presented by the bodies is due to the fact that the electrons, when moving inside the atoms, rub against each other, producing shocks that release energy in the form of heat.
