Question

why led is placed in a circuit​

Answer 1

Answer:

LED in a series circuit

Explanation:

LED in a series circuit

Because the current through all LEDs in series is equal, they should be of the same type. ... The voltage source must provide a large enough voltage for the sum of voltage drops of the LEDs plus the resistor. Typically the voltage source is 50 percent higher than the sum of LED voltages.
