### What is Meant by Resistance?

In Physics, the resistance is defined as the measure which is used to calculate the opposition of the current flow in the electrical circuit. The unit used to measure the resistance is the ohm, and it is denoted by the Greek letter Ω. The resistance depends on the length of the wire and the cross area of the conductor, and the temperature. The formula to calculate the resistance is defined using Ohm’s law. Hence,

Resistance, R = Voltage (V) / Current (I)
