Q: Which of the following is a passive electronic component?

Resistor — Resistors consume energy, transistors and op-amps need power to function.

Q: What is the unit of measurement for electric current?

Ampere (A) — Current is measured in Amperes, often abbreviated as Amps (A).

Q: What is the relationship between voltage (V), current (I), and resistance (R) in a circuit?

V = I * R — This is Ohm's Law: Voltage equals current multiplied by resistance.

Q: Which component blocks DC current but allows AC current to pass through?

Capacitor — Capacitors store energy and oppose sudden changes in voltage.

Q: What is the purpose of a diode?

To allow current flow in one direction only — Diodes act as a one-way valve for current.

Q: What is the unit of measurement for resistance?

Ohm (?) — Resistance is measured in Ohms (?).

Q: What is the function of a transistor?

To amplify or switch electronic signals — Transistors are fundamental for amplification and switching in circuits.

Q: What type of circuit provides a path for current to flow directly from the power source back to itself?

Short circuit — A short circuit offers very low resistance, allowing excessive current flow, which can damage the circuit.

Q: What is the unit of measurement for electrical power?

Watt (W) — Electrical power is measured in Watts (W).

Q: What does a multimeter measure?

Voltage, current, and resistance — Multimeters are versatile tools for measuring various electrical parameters.

Silicon is the primary material used to make semiconductors such as transistors and diodes.

Question 12 of 15

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

Fuses are safety devices that break the circuit when excessive current flows.

Question 13 of 15

What is the symbol for a resistor?

The symbol represents a device that resists the flow of current.

Question 14 of 15

What does 'AC' stand for in AC circuits?

AC stands for Alternating Current, which periodically reverses direction.

Question 15 of 15

What is the color code for a 1 k? resistor with brown, black, and red bands?

Brown=1, Black=0, Red= x100, so 10 x 100 = 1000 ohms or 1 k?.
