15 Questions
Question 1 of 15
What is the SI unit of electric current?
Electric current is measured in Amperes.
Question 2 of 15
Which of the following is the best conductor of electricity?
Copper has low resistance and high conductivity.
Question 3 of 15
What is Ohm's Law?
Ohm's Law states that Voltage (V) = Current (I) * Resistance (R).
Question 4 of 15
What is the function of a resistor in a circuit?
Resistors limit the current flow in a circuit.
Question 5 of 15
What is the unit of electrical resistance?
Resistance is measured in Ohms.
Question 6 of 15
What is the function of a capacitor?
Capacitors store energy in an electric field.
Question 7 of 15
What is the difference between AC and DC current?
DC flows in one direction, while AC reverses periodically.
Question 8 of 15
What is the purpose of a diode?
Diodes conduct current in one direction and block it in the other.
Question 9 of 15
What does the abbreviation LED stand for?
LED stands for Light Emitting Diode.
Question 10 of 15
Which component is commonly used to switch electronic circuits?
Transistors act as electronic switches and amplifiers.
Question 11 of 15
What is the unit of electrical power?
Power is measured in Watts.
Question 12 of 15
What type of circuit allows current to flow through multiple paths?
In a parallel circuit, current has multiple paths.
Question 13 of 15
What is the purpose of a fuse in a circuit?
Fuses break the circuit when excessive current flows.
Question 14 of 15
What is the function of a transformer?
Transformers step up or step down AC voltages.
Question 15 of 15
Which component blocks DC current while allowing AC current to pass?
Capacitors impede DC, but facilitate AC current flow.
