Solution to Frame 51
Let us start on a more technical definition of voltage go on to the next step.
or electromotive force by talking about a battery.
One of the symbols for a battery is shown below.
Draw one for practice here:
You have just drawn the symbol for a __________.
Solution to Frame 52
One side of a battery is always negative. This
means that it has more electrons than it has
Solution to Frame 53
The negative side of the battery has a negative
charge. The positive side has a
