Question 1 of 10
What is the SI unit of electric current?
Electric current is measured in Amperes (A), named after André-Marie Ampère.
Question 2 of 10
Which of the following is the correct expression of Ohm's Law?
Ohm's Law states that Voltage (V) equals Current (I) multiplied by Resistance (R).
Question 3 of 10
What is the primary function of a resistor in an electrical circuit?
A resistor's primary function is to resist the flow of current, dissipating energy as heat.
Question 4 of 10
In a series circuit, what is constant across all components?
In a series circuit, the same current flows through all components.
Question 5 of 10
What is the unit of electrical power?
Electrical power is measured in Watts (W), representing the rate of energy transfer.
Question 6 of 10
What is the relationship between voltage, current, and power?
Power (P) is calculated by multiplying Voltage (V) and Current (I): P = V * I.
Question 7 of 10
What is the total resistance of two resistors (R1 = 10 Ohms, R2 = 20 Ohms) connected in series?
In series, total resistance is the sum of individual resistances: 10 + 20 = 30 Ohms.
Question 8 of 10
What is a short circuit?
A short circuit is a low-resistance path, allowing excessive current flow and potentially damaging the circuit.
Question 9 of 10
What is the purpose of a fuse in an electrical circuit?
A fuse is a safety device designed to break the circuit if the current exceeds a safe level.
Question 10 of 10
Which of these is a passive component?
Resistors are passive components; they consume energy, unlike active components like transistors.
