1. RESISTORS
A resistor is used to reduce the flow of electricity in an electric circuit. Resistorscome in fixed or variable types.

2. A fixed resistor cannot be changed as it is set at a specific value
FIXED RESISTORS

3. Variable resistors also known as rheostats can have their resistance changed by moving a slider.

4. •. Thermistors are resistors whose resistance changes with temperature
• Thermistors are resistors whose resistance changes with temperature. The higher the temperature, the lower the resistance.

5. LIGHT DEPENDANT RESISTOR LDR
An LDR is a component that has a (variable) resistance that changes with the light intensity that falls upon it.

6. A diode is an electrical device allowing current to move through it in one direction with far greater ease than in the other.

7. LIGHT EMITTING DIODE LED
A light-emitting diode (LED) is a semiconductor device that emits visible light when an electric current passes through it.
