Batteries in Parallel Project #23

FOR ADVANCED USERS - ADULT
SUPERVISION RECOMMENDED
1A
Remove parts from the circuit until it looks like
the Part B drawing.
Assembly
Touch the red or black jumper wires to the
metal contacts for the center battery as
shown. The single bulb (L4) will glow brighter
than in the original circuit when only one
battery is connected. Note: Your M5 meter is
a simple meter. It may read zero on this scale
even though a small current is flowing.
Now connecting both batteries at once doesn’t
change the brightness or increase the current
measured, because a single battery can supply
as much current as this simple circuit needs.

Touch the red or black jumper wires to the metal contacts for the
center battery as shown. The bulbs (L4) will barely glow and the
motor (M1) will probably need a push to get it started. The meter
measures the current.
Touching both on at the same time connects both batteries in
parallel. This makes the bulbs glow a little more, makes the motor
spin faster, and increases the current on the meter.
Operation
When batteries are connected in parallel they can supply more
current to a circuit. This means more power.
Description
Remove the center battery from the battery holder (B3). Build the
circuit as shown. Set the meter (M5) to the 1A setting.
