1.5 (a)

Class Experiment 1

The pupils use a mains supply meter to find values of E and I for 60 seconds, in order to calculate values of p.d..

Analysis

Create a table for the data and the subsequent calculated values. Use values of I and t to find Q. Then use the defining equation p.d. = E/Q. Compare values to the mains voltage. They could plot a graph of E vs Q, the gradient will be V

Equipment

All mains supply meters, 1x kettle, 1x lamp, 1x radio, 1x T.V., 1x heater

Syllabus

Motion, Energy & Charge
