Physics 2 0.0 / 5 ? Physicselectric current and potential differenceGCSEEdexcel Created by: laviniahann3Created on: 29-05-17 10:13 What is current? Current is the rate of flow of charge round the circuit 1 of 9 How will current flow? Current will only flow through a component if there is a voltage across that component 2 of 9 What is voltage? Voltage (potential difference) is the driving force that pushes the current round. 3 of 9 What are the measurements for voltage? Volt (V) 4 of 9 What is resistance? Resistance is anything in the circuit which slows the flow down 5 of 9 What are the measurements for resistance? Ohm (Ω) 6 of 9 What will happen if you increase the voltage? If you increase the voltage - then more current will flow 7 of 9 What will happen if you increase the resistance? If you increase the resistance - then less current will flow 8 of 9 What would you have to do to keep the same current flowing when the resistance increases? More voltage will be needed to keep the same current flowing 9 of 9
