PARTS LIST Project 9 Current Divider
Set the meter (M5) to the 1A setting, and push the press switch (S2). The lamps (L4)
come on, and the meter measures the current from the batteries.
Part B: Swap the location of the meter with the 3-snap wire marked “A” (place “+” side
towards L4). Push the switch to measure the current through circuit branch “A”.
Part C: Swap the “A” location of the meter with the “B” 3-snap. Note that M5 will not fit;
just hold it in place for this test. Push the switch to measure the current the “B” branch.
1A
M5 will not fit, so
just hold it in place.
BATTERIES:
● Use only 1.5V AA type (alkaline
recommended, not included).
● Insert batteries with correct polarity.
● Non-rechargeable batteries should not
be recharged. Rechargeable batteries
should only be charged under adult
supervision, and should not be
recharged while in the product.
● Do not mix alkaline, standard (carbon-
zinc), or rechargeable (nickel-
cadmium) batteries.
● Do not mix old and new batteries.
● Remove batteries when they are used up.
● Do not short circuit the battery
terminals.
● Never throw batteries in a fire or
attempt to open its outer casing.
● Batteries are harmful if swallowed, so
keep away from small children.

Part B: Part C:
The current from the batteries splits up between the
two lamps, because they are connected in parallel.
If you add up the current you measured through
circuit branches A & B, it should be the same as the
current you measured from the batteries. (Your
result may be a little different, because M5 is a
simple meter with low accuracy.)
Kirchhoff’s Current Law, an important rule for
analyzing circuits, says that all current flowing into a
point must flow out of it.
