Resistor Circuit Example

Based on the electric potential color-coding, which statement accurately describes the arrangement of resistors R2 and R3?

• R2 and R3 are in series.

• R2 and R3 are in parallel.

• R2 is in series with R3.

• R2 is in parallel with R1.

What is the state of resistor R4 in the given circuit?

• In series with R3

• In parallel with R2

• Short-circuited

• Open-circuited

What is the electric potential difference across resistor R4, and what does this imply about the current through it and the power it dissipates?

• Potential difference is maximum, current is maximum, power is maximum.

• Potential difference is zero, current is zero, power is zero.

• Potential difference is half the battery voltage, current is half the total current, power is half the total power.

• Potential difference is equal to the battery voltage, current is maximum, power is maximum.

Which of the following is a limitation of the animated model showing charge movement in the circuit?

• The model accurately depicts the movement of electrons.

• The charges shown are of realistic size.

• The charges move in perfectly straight lines.

• The model shows positive charges moving, while electrons (negative charges) actually move.
