Resistance 4.0 / 5 based on 1 rating ? PhysicsElectricityGCSEOCR Created by: emilysworldCreated on: 27-04-19 08:25 What is resistance? The property of a material to reduce the flow of electrical current due to collisions of free electrons 1 of 7 What is the equation for resistance? resistance = potential difference/current 2 of 7 What is the unit for resistance? Ohms 3 of 7 What is the unit for potential difference? Volts (V) 4 of 7 What is the unit for current? Amps (A) 5 of 7 How does the length of a wire affect its resistance? Increasing the length of the wirwee will increase the resistance 6 of 7 How does the thickness of a wire affect its resistance? The thicker the wire, the lower the resistance 7 of 7
