Experiment 5: Let’s Make a Battery

38 Chapter 1

Same

resistance

Higher voltage

Greater force

creates more flow,

because amperage =

voltage / resistance,

and the voltage has

gone up, while

the resistance

has remained

the same.

Higher

water level

Figure 1-79. Greater force generates more flow, as long as the resistance remains the

same.

1.5 volts

3 volts

Figure 1-80. When you place two equal batteries in

series, you double the voltage.

1.5 volts

for twice as long

Figure 1-81. Two equal batteries that are wired in parallel

will deliver the same voltage for twice as long as one.
