A measure of the rate of flow of charge through a point in a circuit. 2 of 9 An Ohmic conductor.. Has a consant resistance when voltage and current change. 3 of 9 What is potential energy? The energy in Joules transfered to a component for each coulomb of charge that passes through it. 4 of 9 Thermistors are made from.... Semiconducting material 5 of 9 In a potential divider circuit..... Voltage is shared between resistors in the same ratio as their resistances. 6 of 9 What does the volume control on a radio use? A potentiometer 7 of 9 Why are solar cells connected in parallel rather than series? There is less internal resistance and therefore more ouput current when connected in Parallel. 8 of 9 What does HEP stand for? Hydroelectic power 9 of 9
