Solution to Frame 23
To move a wagon uphill, you must apply a force. To move
electrons through a resistor, a battery must also apply
Solution to Frame 24
When you move a wagon uphill, force is used up. When
a force (or a voltage)
electrons are pushed through a resistance, electromotive
force (EMF) is also _______________________.
Solution to Frame 25
When EMF is used up, the voltage drops. Across any
resistance, EMF is used up and the voltage ____________.
Solution to Frame 26
The drop in voltage is called voltage drop.
Across the resistor above, we have a 10v ______________.
Solution to Frame 27
In the diagram below, the voltage drop across R1 is ______
and across R2, it is _________.
