Answer 1

according to the principal of LDR and

resistance are used

I think b is correct....♥️♥️♥️♥️♥️♥️♥️♥️♥️

Answer 2

Answer:

Option(c) Automatic function of street light is done by Thermistor.

Explanation:

• By varying the street lights from time to time and, in certain circumstances, toggling as well as turning OFF of some lights concerning the motion observed on the roads, smart automatic street light system helps in controlling the street lights intelligently and automatically to minimize power consumption and reduces man work.

• Thermistor -A thermistor is a resistor whose resistance is temperature-dependent or a resistance thermometer.

• Thermistors are a highly accurate and economical temperature sensor, deriving from the word thermally sensitive resistors.

• A transistor is used as a switch in the automatic street light system, which is a straightforward idea.

• When the light level falls below ambient light, the lights turn on automatically. LDR, which detects light, is used for this.
