Answer 2

The device which can be used to detect very small current flowing in an electric circuit is D. LED

Explanation:

• Light emitting diode is a simple circuit of anode and cathode.
• It can only work in forward bias but it cannot work in reverse bias which means the current can only flow from anode to cathode.
• The anode has longer lead compared to cathode.
• The brightness of the LED depends on the current passing through it.
• There are many types of LEDs include RGB LEDs, Addressable LEDs and so on.
