Example questions

Let's look at some sample questions

Which component is used to store electrical energy in a circuit?

CapacitorResistorInductorDiode
A capacitor stores electrical energy. This is a basic property of capacitors and is widely known in electrical engineering.

A 12V battery is connected to a 6 Ohm resistor. What is the current flowing through the circuit?

2 A1 A3 A4 A
Using Ohm's Law (I = V/R): I = 12V / 6 Ohm = 2A. Verification: First calculation, 12 / 6 = 2A; Second, confirmed same result; Third, confirmed same result. Correct answer is 2A.

Which unit is used to measure electrical current?

VoltWattAmpereOhm
Current is measured in Amperes (A) according to the International System of Units.

In a circuit, how much current flows if a 9V battery is connected across a 45Ω resistor?

0.2A0.1A0.25A0.3A
Ohm's law states I = V/R. Here, V=9V and R=45Ω. Calculating current I = 9V / 45Ω = 0.2A. Verifying: I = 9V / 45Ω = 0.2A; I = 9V / 45Ω = 0.2A; I = 9V / 45Ω = 0.2A.

What is the main purpose of a circuit breaker in a distribution board?

Increase powerStep down voltageOvercurrent protectionConvert AC to DC
Circuit breakers protect against overcurrent, interrupting the flow to prevent damage.

Which component is essential for synchronizing generators in parallel operation?

Load resistorGovernorSynchronizerInductor
A synchronizer is used to match the phase, frequency, and voltage of generators before synchronizing them in parallel.

What type of current is used in most shipboard power generation?

DCACPulsed DCMixed
AC is used for shipboard power generation due to its efficiency in power transmission over distances and ease of transformation.

For a generator on a ship, what causes harmonic distortion in the power output?

Resistive loadsNon-linear loadsBalanced loadsReactive power
Harmonic distortion typically arises from non-linear loads such as variable frequency drives or rectifiers which distort the current waveforms.

What does PPE stand for in electrical safety?

Personal Protective EquipmentPower Protection ElementPrimary Protective EarthingPortable Power Enclosure
PPE stands for Personal Protective Equipment, essential for ensuring safety when working with electrical systems.

Which PPE offers maximum protection against arc flash hazards?

Safety gogglesLeather glovesFlame-resistant clothingRubber boots
Flame-resistant clothing is designed to withstand arc flash temperatures, offering maximum protection by preventing serious burns or injuries in such scenarios.
