Electric Circuits Quiz

What is the purpose of tracing a circuit?

• To calculate the total resistance

• To determine the number of bulbs in the circuit

• To identify possible pathways for electric current

• To find the shortest path for current

How many possible pathways are there for electric current in circuit B?

• Four

• Two

• One

• Three

In circuit A, how is the power distributed among the bulbs?

• Each bulb receives power from one battery

• Each bulb receives power from 1.5 batteries

• Each bulb receives power from two batteries

• Each bulb receives power from three batteries

Which bulb receives the most power in circuit B?

• Bulb P

• Bulb Q

• Bulb R

• Bulb S

How many batteries are there in circuit C?

• Four

• Two

• One

• Three

What happens to bulb S when bulb R is removed in circuit B?

• Bulb S goes out

• Bulb S remains lit

• Bulb S becomes brighter

• Bulb S flickers

Why does bulb S remain lit when bulb R is removed in circuit B?

• Because the bulbs are in series

• Because the circuit is closed

• Because the bulbs are in parallel

• Because the circuit is open

In a parallel circuit, what happens when one bulb fuses?

• Other bulbs remain lit

• The circuit becomes closed

• The circuit becomes open

• All bulbs go out

What is the first step in the four-step method for circuit analysis?

• Check if current flows

• Determine if the circuit is open or closed

• Determine the outcome

• Identify the situation

What is the final step in the four-step method for circuit analysis?

• Determine the outcome

• Identify the situation

• Determine if the circuit is open or closed

• Check if current flows
