Solution and Explanation
The main components of an immersion heater are:
Heating element: Usually made of nichrome or copper wire wound on an insulating core that heats up when electric current passes.
Insulating sleeve: Protects the heating element and prevents short circuit with water.
Metal sheath: Covers the heating element and insulation, usually made of copper or stainless steel to prevent corrosion.
Thermostat: Controls the temperature by switching the heater ON/OFF.
Terminal box: Contains electrical connections and provides a safe entry point for wires.
Protective casing: Outer body protecting the entire assembly.
