ACR-206 Chapter 10 Pre/Post Test

What components are included in a basic electrical circuit?

• Power supply, fuse, switch, load, and wires

• Battery, resistor, capacitor, and diode

• Transformer, inductor, relay, and motor

• Generator, alternator, inverter, and rectifier

According to the conventional theory of current flow, what is the positive pole?

• The return side of the circuit

• The supply side of the circuit

• The ground pole

• The neutral side

What is the resistance of an open circuit?

• Zero resistance

• Low resistance

• Infinite resistance

• High resistance

What effect does unintended high resistance have in a circuit?

• Increases amperage

• Reduces amperage

• Increases voltage

• Reduces voltage

What are the three basic units of electrical measurement?

• Volts, watts, and joules

• Volts, amps, and ohms

• Amps, ohms, and watts

• Joules, coulombs, and volts

What does circuit resistance determine?

• Voltage drop

• Power consumption

• Amperage drawn

• Frequency

What is Ohm’s Law formula?

• V = I × R

• A = V × R

• P = V × I

• R = V / I

How is voltage drop calculated?

• Voltage Drop = Resistance × Current

• Voltage Drop = Amperage × Resistance

• Voltage Drop = Amperage / Resistance

• Voltage Drop = Resistance / Amperage

Why do circuits fail most of the time?

• Due to high voltage

• Due to low or non-existent current flow

• Due to high resistance

• Due to low resistance

What are the two basic configurations of circuits?

• Series and parallel circuits

• Open and closed circuits

• High and low resistance circuits

• AC and DC circuits
