AQA Physics GCSE Student calculation sheet Name.... Class P5.4 To calculate the energy supplied we need to use the equation E-VxQ E= 12 x 150 = 1800 J Step 4: And finally, to calculate power = E or V x I Date So power = 1800 30 60 W Questions 1 the terminals? The potential difference between the two terminals on a battery is 9 volts. How much work (energy) is required to transfer 10 coulombs of charge across of 2 10 joules of work (energy) is required to transfer 2 coulombs of charge from X to Y. What is the potential difference between these two points? ont of a 3 To transfer a quantity of charge between points C and D of a circuit, which have a potential difference of 30 volts, 600 joules of energy is required.
