Components Of Bike Light Funcction

Question 1

Name the components

Answer 1

Battery, LED, Switch, LDR, Transistor (base collecter emitter), VR

Question 2

Battery function

Answer 2

This is the power source for the circuit and it provides the voltage

Question 3

LED function

Answer 3

Light Emitting Diode- A component that gives off light when current flows through it

Question 4

Switch function

Answer 4

Makes or breaks the flow of a current

Question 5

LDR function

Answer 5

Light Dependent Resistor- Is a type of resistor that senses light. High resistance when light levels are low and low resistance when light levels are high

Question 6

Transistor function

Answer 6

Sensitive Electronic Switch- When current is detected at the base of the Transistor it turns on and a larger current flows from the collector to the emitter.

Question 7

VR function

Answer 7

Variable Resistor is a type of a resistor that allows you to change he value of its resistance
