Question

when small current passing throw circuit , it is dected by 1) LED
2) Bulbs
3) Tube light
4) Incandescent bulbs​

Answer 1

Answer:

LED:

Explanation:

• Light Emitting diode is a simple circuit of anode and cathode.
• Light Emitting diode is a simple circuit of anode and cathode.it can only work in forward bias but cannot work in reverse bias which means the current can flow from anode to cathode.
• Light Emitting diode is a simple circuit of anode and cathode.it can only work in forward bias but cannot work in reverse bias which means the current can flow from anode to cathode.the anode has longer lead compared to cathode.
