4. A filament is located inside the glass case of the bulb. 5. A torch reflector helps to spread light by reflecting it. 6. A bulb does not glow when current flows through the closed circuits. 7. Silver is the best conductor of electricity. 8. Switches, electrical plugs and sockets are made of conductors.​

Answer 1

Answer:

filament is made of Nicrhomia wire it has a very high resistivity and when current is goes from it converts electric energy to light energy 5. convex lens 6.maybe circuit is broken or switch is off 7. because silver have very low resistivity 8.copper wire i think maybe it's help you
