Lab
 Take
out your series circuit work sheet.
 Find something to write with and a piece of paper
for your group.
 You will be grouped by row today.
Directions
 Part

1
Measure the voltage of the battery.
 Turn
the dial to 20 on the multi-meter (top left)
 Place one probe on the positive (+) and one probe on
the negative (-) end.
 Record the voltage.
 Part

2
Measure the resistance of the resistors
 Turn
the dial to 20 (bottom left)
 Place a probe on each side of the resistor
 Record the resistance for each resistor (green, blue,
and red)
Series Circuit Simulation
 Re-create
the circuit from question one and
six from the series circuit work sheet.
 Measure the voltage, resistance, and current
in the circuit.
 Compare the worksheet values to the
simulations values and summarize your findings
using academic vocabulary (measuring
devices, voltage, resistance, current, etc.)
Parallel Circuit Simulation
 Re-create
the circuit from question five and six
from the parallel circuit work sheet.
 Measure the voltage, resistance, and current
in the circuit.
 Compare the worksheet values to the
simulations values and summarize your findings
using academic vocabulary (measuring
devices, voltage, resistance, current, etc.)
Project
 You
will work in groups of three (groups larger
than three need my approval).
 The project is a test grade.
 You can use any of the circuit supplies in the
back to make your circuit. The only limitation is
that it needs to fit on a circuit board.
 You need to make a series and a parallel circuit
(if you want to combine them and make a
complex circuit you may do so).
