Simplify Ohm’s Law
Students often have trouble rearranging the equation
for Ohm’s law. Show them the fol lowing diagram to go
with the expression V = IR. When the desired variable
is covered, the other two variables are in appropriate
mathematical order.

AP4653 Battery Holder, D-cell with Wire Clips $2.69
Battery Pack
This cleverly designed battery holder keeps four D-cell batteries in series. By attaching
the included leads to zinc terminals at various locations you can get 1.5V, 3V, 4.5V
or 6V without removing or touching the batteries. The molded plastic feet on the
bottom of the holder prevent the batteries from rolling off your work surface. The
battery pack comes with complete operating instructions. D batteries sold separately.

batteries can be clipped together
depending upon the voltage
required.
