POE - Electricity Intro

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

• To provide voltage

• To consume electrical power

• To allow current to travel

• To limit current travel

What is the unit of measurement for electrical rate of flow?

• Ohms

• Volts

• Ampere

• Load

In the water system analogy, what is equivalent to a switch in an electrical circuit?

• Water wheel

• Faucet valve

• Water tank

• Pipe

What is the unit of measurement for electrical resistance?

• Volt

• Ampere

• Ohm

• Watt

How is voltage often described in terms of its effect in a circuit?

• As electrical volume

• As electrical speed

• As electrical density

• As electrical pressure

What is the purpose of using a breadboard in circuit design?

• To increase circuit resistance

• To measure voltage and current

• To temporarily build and test circuits

• To permanently fix components

Which of the following is NOT a basic component of an electrical circuit?

• Power Source

• Conductor/Wire

• Insulator

• Load/Component

What does a multimeter measure in a circuit?

• Voltage, current, and resistance

• Only resistance

• Only current

• Only voltage

What happens to current when resistance increases in a circuit?

• Current increases

• Current decreases

• Current remains the same

• Current fluctuates

What is the advantage of using fewer wires on a breadboard?

• It increases the circuit's current

• It reduces the circuit's voltage

• It makes troubleshooting easier

• It increases the circuit's resistance
