Hi Colin, I did mine in April this year in Blackburn. The assessor is helpful and doesn’t want to fail anyone. I doubt all theory parts are the same, but I got questions on - Resistors in parallel Resistors in series Calculating capacitance in a circuit Calculating motor efficiency Calculating the power of a circuit using the resistance Calculating turns on a transformer winding There were also questions around selection of motors, thermostats, smoke detectors. There were a few easy questions too that anyone could answer! Good luck with it! Andy
