15 Questions
Question 1 of 15
What is the unit of electric current?
Current is the flow of electric charge, measured in Amperes.
Question 2 of 15
What does Ohm's Law describe?
Ohm's Law (V=IR) relates voltage, current, and resistance in a circuit.
Question 3 of 15
What is the unit of electrical resistance?
Resistance opposes current flow, measured in Ohms.
Question 4 of 15
Which of the following is a passive electronic component?
Resistors are passive components, not providing gain or directionality.
Question 5 of 15
What is the unit of voltage?
Voltage is the potential difference, measured in Volts.
Question 6 of 15
What is the purpose of a resistor in a circuit?
Resistors limit current flow in a circuit.
Question 7 of 15
Which component is used to store electrical energy?
Capacitors store energy in an electric field.
Question 8 of 15
What is the purpose of a diode?
Diodes conduct current in only one direction (like a one-way valve).
Question 9 of 15
What is the SI unit of power?
Power is the rate at which energy is used, measured in Watts.
Question 10 of 15
Which of the following is a type of electrical circuit?
Series, parallel and series-parallel are all circuit configurations.
Question 11 of 15
What type of signal is typically used by batteries?
Batteries supply direct current (DC).
Question 12 of 15
What is the formula for calculating power (P) in a DC circuit?
Power is the product of voltage and current (P=VI).
Question 13 of 15
What is the purpose of an inductor?
Inductors store energy in a magnetic field.
Question 14 of 15
What is a short circuit?
A short circuit offers a low-resistance path, leading to high current.
Question 15 of 15
Which component is commonly used to switch electronic signals?
Transistors can be used as electronic switches to control the flow of current.
