A series circuit has three resistors, each on different paths and connected to a 120 V battery. Resistor 1 has a resistance of 5.0 Ω, Resistor 2 has a resistance of 7.5 Ω, and Resistor 3 has a resistance of 9.5 Ω. Create the circuit using the PhET simulator, and then draw a picture of the circuit you
made. Then, fill in the table below for this circuit. Show your work completed.
Measurements and the
corresponding units Resistor 1 Resistor 2 Resistor 3 Total
V (volts) 120 V
I (A – amperes)
R (Ω – ohms) 5.0 Ω 7.5 Ω 9.5 Ω
P (W – work)
Show your work: I=Vtotal/Rtotal. This gives you the total, I, which then allows you to calculate Ohm’s law
for the other individual resistors. The total voltage spread across the three resistors should equal
the total number of voltage periods. The power is determined by P 5 I 3 V
