Okay, Anthony, let's continue with these questions. c) TWO effects of electric current and their automobile applications are: • Heating Effect: Electric current flowing through a conductor generates heat due to resistance. Automobile application: Car heater/defroster* (uses resistive elements to generate heat for cabin warming or window defrosting). • Magnetic Effect: Electric current flowing through a conductor produces a magnetic field around it. Automobile application: Starter motor* (uses the magnetic field created by current in coils to turn the engine's flywheel). d) FOUR safety measures to be observed when working on electrical appliances are: • Always disconnect the power source (unplug or switch off the circuit breaker) before starting any work. • Use insulated tools to prevent accidental contact with live wires and reduce the risk of electric shock. • Ensure the work area is dry and free from moisture to avoid creating conductive paths for electricity. • Inspect power cords and plugs for any damage (frays, cuts, exposed wires) and replace them if necessary before use. 3 done, 2 left today.
