Electricty P3 0.0 / 5 ? ScienceElectricityGCSEOCR Created by: cherryblair78Created on: 28-01-23 08:15 How is static charge created? Built up friction when two insulators rub together. 1 of 15 When electrons transfer in static charge, what happens when the object gains electrons? A negative Charge 2 of 15 When electrons transfer in static charge, what happens when the object loses electrons? A positive Charge 3 of 15 What is an electric field? A region where electric charge creates a force. 4 of 15 When is an electric field strongest? Near a charged object. 5 of 15 What is potential difference? The measure of energy transferred. 6 of 15 What is P.D. measured in? Volts 7 of 15 What is resistance? How difficult it is for current to flow. 8 of 15 What is resistance measure in? Ohms 9 of 15 What is current? Rate of flow of electric charge. 10 of 15 What is current measured in? Amps 11 of 15 What equation links charge, current and time? charge flow= current x time 12 of 15 Calculate potential difference: Current x resistance 13 of 15 Calculate resistance: Potential difference/ current 14 of 15 Calculate current: potential difference/ resistance 15 of 15
