What is the primary function of a diode in a circuit?

• To allow current to flow in both directions.

• To allow current to flow in one direction only.

• To store electrical energy for later use.

• To amplify electrical signals.

How can you identify a short circuit in an appliance?

• Frequent appliance upgrades

• Increased energy bills

• Flashing lights on the appliance

• Signs of burning & tripped breakers.

What is the purpose of a fuse in an electrical circuit?

• To protect the circuit from overcurrent.

• To store electrical energy for later use.

• To increase the voltage in the circuit.

• To enhance the circuit's efficiency.

What does the symbol 'C' stand for in electronic diagrams?

• Capacitor

• Conductor

• Current

How can you test a resistor with a multimeter?

• Connect the probes to a power source and check for current flow through the resistor.

• Set the multimeter to the voltage setting and measure the voltage across the resistor.

• Use a continuity setting to check if the resistor is functioning properly.

• Set the multimeter to the resistance setting, connect the probes to the resistor's leads, and read tvalue.

What is the function of a capacitor in a circuit?

• A capacitor converts electrical energy into heat.

• A capacitor stores and releases electrical energy in a circuit.

• A capacitor acts as a fuse to protect the circuit.

• A capacitor amplifies electrical signals in a circuit.

What does it mean if a circuit is open?

• A circuit is open when there is a break in the path.

• A circuit is open when it has too much current flowing through it.

• A circuit is open when it is powered on and functioning normally.

• A circuit is open when all components are connected properly.

Which tool is commonly used to measure voltage in a circuit?

• Voltmeter

• Multimeter

• Ammeter

• Ohmmeter
