Electronic transistor

What is the function of an electrical transistor?

• To slow down the flow of electrical current

• To ensure the current flows only in one direction

• To store electrical energy and supply it to the circuit when needed

• To amplify current or to act as a switch in a circuit

Match the following

• Diode

• 
• Resistor

• 
• Capacitor

• 
• Transistor

• 

Which of the following is NOT the terminal of a transistor?

• Anode

• Emitter

• Base

• Collector

There are 2 types of transistor which are

How does a transistor works as a switch?

• Current flows from the source to the drain

• The channel then becomes conductive

• Apply a voltage at the base which is greater than the activation voltage

• The transistor is turned on

What is the term we used to describe adding dopant or impurities to the transistor to improve conductivity?
