What does AC stand for in electrical terms?

• Amplified Current

• Alternating Current

• Analog Converter

• Advanced Circuit

Define Ohm's Law and provide the formula.

• V = IR

• R = V/I

• I = V/R

• I = R/V

Explain the difference between series and parallel circuits.

• In series circuits, components are connected in a single path, while in parallel circuits, components are connected in multiple paths.

• Parallel circuits have only one component, while series circuits have multiple components.

• Series circuits have higher voltage than parallel circuits.

• In series circuits, components are connected in multiple paths, while in parallel circuits, components are connected in a single path.

What is the purpose of a ground wire in an electrical system?

• To prevent electrical current from flowing through the system

• To regulate the voltage in the system

• To increase the resistance in the circuit

• To provide a path for excess electrical current to flow into the ground

What is the role of a transformer in electrical circuits?

• To convert electrical energy into heat

• To transfer electrical energy between circuits through electromagnetic induction and adjust voltage levels.

• To store electrical energy in batteries

• To generate electricity from mechanical energy

What is the difference between a resistor and a capacitor?

• A resistor stores energy, a capacitor limits current flow.

• A resistor limits current flow, a capacitor stores and releases energy.

• A resistor and a capacitor are the same thing.

• A resistor releases energy, a capacitor limits voltage.

Explain the concept of electrical power and how it is calculated.

• Electrical power is not related to voltage or current.

• Electrical power is measured in volts.

• Electrical power is calculated by multiplying the voltage (V) across the circuit by the current (I) flowing through it using the formula P = V * I.

• Electrical power is calculated by dividing the voltage by the current.

What safety precautions should be followed when working with electricity?

• Wearing sunglasses

• Swimming while working with electricity

• Using wet hands

• Follow safety precautions such as wearing PPE, grounding equipment, avoiding water, using insulated tools, and turning off power.

Discuss the importance of electrical codes and regulations in the industry.

• Electrical codes and regulations are important for safety, standardization, and legal compliance in the industry.

• Electrical codes and regulations are unnecessary burdens in the industry.

• Following electrical codes and regulations is optional for companies.

• Electrical codes and regulations hinder innovation and progress in the industry.

What is the primary function of a fuse in an electrical circuit?

• To increase the current flow

• To decrease the resistance

• To interrupt the circuit in case of excessive current

• To convert AC to DC
