The energy provided to the circuit, also known as potential difference.
A component within a circuit that limits the current flowing through.
What is voltage?
The amount of charge moving through an object or circuit over time.
The energy provided to the circuit, also known as potential difference.
A component within a circuit that limits the current flowing through.
What is a resistor?
The amount of charge moving through an object or circuit over time.
The energy provided to the circuit, also known as potential difference.

What does it mean for two resistors to be in parallel?
The resistors are on the same loop and have the same current.
The resistors are on different loops separated by junctions.
What does it mean for two resistors to be in series?
The resistors are on the same loop and have the same current.
The resistors are on different loops separated by junctions.
What does the junction rule state?
Total current entering the junction must equal total current exiting the junction.
The voltage drop of two resistors in series must be equal.
Total potential difference (voltage) around a closed loop must be equal to zero.
Equivalent resistance is equal to the sum of the resistance measurements of all resistors in a loop.
