Question

a)In the given diagram the wire A become hot when electric current pass through circuit. Identify A,B,C,D.
b)How does a bulb convert electric energy to light energy​

Answer 1

Answer:

A is a warm wire of any high melting point metal ..

B is a simple current conducting wire

C is a battery

D is a switch .

b) by heating effect of current

Answer 2

Answer:

Identification of A, B, C, and D are given below

Explanation:

(a):

• A: a wire with a high melting point. We chose a wire with a high melting point because normal conducting wires would melt due to high heat generation.
• B: is a normal conducting circuit wire
• C: is a battery
• D: normal open/off switch

(b):

In a light bulb, the filament is heated by the flow of electric charge and glows. In this way, the light bulb converts electrical energy into thermal energy and light energy.
