Which of the following is the function of a capacitor?
To block current from flowing through the circuit
To amplify the current
To ensure the current flows only in one direction
To discharge electrical charges and provide electrical energy to the circuit when needed
Match the following
Resistor
Diode
Battery
Capacitor
Light emitting diode
How does a diode works?
The n-region has excess electrons
The p-region has less electrons
To achieve balance, the electrons from the n-region move to the p-region and the positive charges move from the p-region to the n-region
Once they move to the other region, a depletion region is formed
Which of the following is the symbol for a capacitor?
What is the unit of measurements for Capacitance?
Farads
Ohms
Volts
Coulombs
What is the unit of measurements for Resistance?
Farads
Ohms
Volts
Coulombs
How does a capacitor works?
The battery provide positive and negative charges to each terminal of the capacitor
The negative charges is attracted to the positive terminal while the negative terminal gains negative charges
When there is no power supply, the capacitor releases the extra charges as electrical energy
Match the following
Forward-biased
Reverse-biased
Depletion region
Match the following
Provides resistance by slowing down the flow of current
Ensuring the current to flow in one direction
Charges and discharges to supply current to the circuit
Provide power supply to the circuit
A conductor to allow current flows in the circuit

Collector
How does a transistor work as a switch?
Apply voltage at the base which is greater than the activation voltage
The channel then becomes conductive
Current flows from the source to the drain
The transistor is turned on
What is the function of an electrical transistor?
To slow down the flow of current
To ensure current flows only in one direction
