Module 7 EXERCISES

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

• Capacitor

• 
• Diode

• 
• Resistor

• 
• Light emitting diode

• 
• Battery

• 

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

• Depletion region

• 
• Forward-biased

• 
• Reverse-biased

• 

Match the following

• Ensuring the current to flow in one direction

• 
• Provide power supply to the circuit

• 
• Provides resistance by slowing down the flow of current

• 
• A conductor to allow current flows in the circuit

• 
• Charges and discharges to supply current to the circuit

• 

Match the following components to their symbol

• Light emitting diode

• 
• Resistor

• 
• Diode

• 
• Battery

• 
• Capacitor
