Question

(i) Study the diagram and name the parts marked as A, B, C, and D. 
(ii) Write the function of A and C.

 

Hint:

The heating element is the part that directly converts electrical energy to heat in devices like electric heaters and irons.

Answer 1

Part A: This diagram illustrates a standard electric heater or electrical appliance. Here's a breakdown:
- A signifies the heating element.
Part B: Component B is the insulating material. It safeguards the electrical components and ensures safety by preventing electrical leakage.
Part C: Part C represents the wire wrapped around the heating element, which carries current through the element.
Part D: Part D designates the metal casing or outer surface, providing both housing for internal parts and mechanical protection.
Functions: Function of A (Heating element): It produces heat when electricity flows through it. This heat then transfers to the surrounding area or the object needing heat.
Function of C (Wire): It facilitates the flow of electrical current to the heating element, enabling the conversion of electrical energy into heat.
