1. Describe the difference in response time between magnetically triggered and
thermally triggered circuit breakers.
Magnetically triggered circuit breakers trip immediately, while
thermally triggered ones have a delay.
Thermally triggered circuit breakers trip immediately, while
magnetically triggered ones have a delay.
Both types trip immediately under the same conditions.
Magnetically triggered circuit breakers are used for low currents, while
thermally triggered ones are for high currents.
2. Describe why it is critical to use a circuit tester before performing
maintenance on electrical circuits.
Using a circuit tester is critical to prevent electrical shock by
confirming the circuit is de-energized.
A circuit tester helps in identifying faulty components in the circuit.
A circuit tester is used to measure the current flowing through the
circuit.
It is important to check the circuit's resistance before working on it.
3. In a series circuit, how does the current behave across different
components?
The current increases across each component.
The current through each component is the same.
The current decreases across each component.
, The current varies randomly across components.
4. If an inductor is in an AC circuit, and the frequency increases,
inductive reactance decreases
neither of these frequency does not affect inductors in AC circuits
inductive reactance increases
5. If an electrical device is designed to convert electrical energy into
mechanical energy, which of the following would be a suitable example of
such a device?
A battery charger
A light bulb
An electric motor
A toaster
6. What is the formula used to calculate the total inductance of inductors
connected in series?
Lt = L1 + L2 + L3
Lt = L1 - L2 + L3
Lt = L1 * L2 * L3
Lt = L1 / L2 / L3
7. Describe the significance of the formula for total inductance in parallel
circuits and how it differs from series circuits.
The formula indicates that inductance in parallel is additive, similar to
series circuits.
, The formula demonstrates that inductance in parallel is equal to the
largest individual inductor.
The formula for total inductance in parallel circuits shows that the
total inductance is less than the smallest individual inductor, unlike
series circuits where total inductance is the sum of all inductors.
The formula is irrelevant for understanding inductance in series
circuits.

currents.
The total current in a parallel circuit is the maximum branch current.
The total current in a parallel circuit is the sum of the individual
branch currents.
