Fun with Electronics

What is this component?

• A transistor

• A Capacitor

Name one type of transistor.

• Diode Transistor (DT)

• Operational Amplifier (Op-Amp)

• Bipolar Junction Transistor (BJT)

• Field Effect Transistor (FET)

What is this Component?

• A capacitor

• A Transistor

What happens when a capacitor is fully charged?

• The capacitor continues to draw current indefinitely.

• The capacitor holds maximum charge and stops current flow.

• The capacitor explodes due to excess charge.

• The capacitor discharges instantly into the circuit.

How does an LDR work?

• An LDR generates electricity when exposed to light.

• An LDR is a type of battery that stores light energy.

• An LDR changes resistance based on light intensity.

• An LDR functions by emitting light when it gets dark.

Can you name one use of an LDR?

• Solar panel energy storage

• Temperature sensors in refrigerators

• Automatic street lights

• Motion detectors for security systems

What is the function of a capacitor in a circuit?

• The function of a capacitor in a circuit is to store and release electrical energy.

• To measure voltage in a circuit.

• To convert AC to DC.

• To amplify electrical signals.

How do you charge a capacitor?

• Place the capacitor in a magnetic field.

• Connect the capacitor directly to a resistor.

• Connect a voltage source to the capacitor's terminals.

• Submerge the capacitor in water.

What is a basic circuit design principle?

• Design for maximum complexity

• Design for minimal components

• Design for functionality and safety.

• Design for aesthetics and cost

What happens when you turn off a transistor switch?

• The transistor stops conducting current and opens the circuit.

• The transistor switches to a higher resistance mode and increases current flow.

• The transistor continues to conduct current and closes the circuit.

• The transistor generates heat and damages the circuit.
