    Key Questions:

    1. How are current, potential difference and resistance linked by an equation?
      • current, potential difference or resistance can be calculated using the equation: potential difference = current ? resistance V= = I R
    2. What does the current through a component depend on?
      • The current (I) through a component depends on both the resistance ? of the component and the potential difference (V) across the component.
    3. What is the difference in function between a resistor and a variable resistor?
      • Resistors have a constant value of R, whereas a variable resistor can change the value of R as the current changes.
