Choose the best option for each question.

1. What causes the heating effect in an electric wire?
   a) Magnetic fieldsb) Electrons colliding with atoms as they flowc) Chemical reactionsd) Radiation from the battery
2. What does a fuse do in a circuit?
   a) Increases the currentb) Stores electrical energyc) Melts to break the circuit if current is too highd) Converts electricity to light
3. If you double the current through a wire, how does the heat change?
   a) Doublesb) Halvesc) Quadruples (increases 4 times)d) Stays the same

Write T for True or F for False in the brackets.
