CP Ch09.7 Series Circuits

What is the characteristic of current in a series circuit?

• It varies throughout the circuit

• It is the same throughout the circuit

• It is inversely proportional to resistance

• It is directly proportional to resistance

What is the main disadvantage of a series circuit?

• All devices must be turned on simultaneously

• If one device fails, the entire circuit ceases

• It is difficult to troubleshoot

• Devices consume more power

How are devices connected in a series circuit?

• In parallel pathways

• In a single pathway

• In a random order

• In a circular pathway

What is required for electrons to flow along a path in a circuit?

• A complete circuit with no gaps

• A single wire

• A broken circuit

• A disconnected battery

How can an electric switch be used to control the energy flow in a circuit?

• By opening or closing the switch

• By rotating the switch

• By pressing the switch multiple times

• By shaking the switch

In a series circuit, what is the relationship between the voltage drop across each device and its resistance?

• They are inversely proportional

• They are directly proportional

• They are unrelated

• They are randomly distributed

Why are most circuits wired in parallel?

• To allow independent operation of multiple electrical devices

• To increase the resistance in the circuit

• To decrease the voltage in the circuit

• To limit the flow of current in the circuit
