Revise Edexcel GCSE Physics 10.3 Electrical energy and power with the question bank, lessons, revision guides, and flashcards.
Recall that, when there is an electric current in a resistor, there is an energy transfer which heats the resistor. • Explain that electrical energy is dissipated as thermal energy in the surroundings when an electrical current does work against electrical resistance. • Explain the energy transfer (in 10.22 above) as the result of collisions between electrons and the ions in the lattice.
