How Do You Determine The Resistance Of A Resistor?

A resistor opposes the electric current flowing through it. This is known as electrical resistance and is measured in ohm.

• Resistance can be calculated with Ohm’s law when the current is known and the voltage drop is measured.
• The resistance is dependent on the shape and material of the resistor.

Resistance = decrease of voltage through a resistor/current flowing through a resistor.

R = IV 

Where V = voltage difference between the two ends of a resistor (V)

R = resistance (Ω)
