PHET Building Circuits Simulation

How does the video suggest you should connect wires in a series circuit?

• In random order

• Using straight lines and right angles

• Any way that is convenient

• With curves and bends2

How many bulbs are initially built into the series circuit?

• One

• Two

• Three

• Four

What measurement does the voltmeter provide?

• Current flow

• Voltage difference

• Resistance

• Length of the circuit33

When measuring current in a series circuit, where can the current meter be placed?

• Anywhere in the circuit

• Only at the beginning

• Only at the end

• It cannot be placed

How does the video suggest you can control a circuit?

• By adding more wires

• By using a switch

• By removing the battery

• By changing the bulb

In a series circuit, what happens to the current when more bulbs are added?

• The current increases

• The current becomes zero

• The current stays the same

• The current decreases

What is a key feature of parallel circuits mentioned in the video?

• All bulbs must be the same brightness

• They require more batteries

• The voltage across each bulb is the same

• They only work with one bulb

What should you observe regarding the brightness of bulbs in parallel circuits?

• They are always equally bright

• They can be different brightness levels

• They do not light up

• They flicker
