made up of a number of smaller single cell batteries (like a 1.5V). Let's say its total voltage is V.
A. Which resistor takes the most voltage?
B.
What is the total resistance?

In variables, what is the current in the circuit?
D.
How does the voltage used by the 2R compare with R?
E. In variables, what is the voltage used by the 2R resistor?
Answer the following questions.
1. Why does the voltage across the resistor for charging and discharging processes
change the sign from positive to negative? Hint: think about the direction of current.
2. Does the voltage V across the resistor for charging and discharging obey by the same
equation: V = Vo eRC
3. What is the sum of the voltages across the capacitor Vc and across the resistor VR at
any point in time during the charging and discharging processes?
Use a snipping tool to copy and paste the waveform chart and graph for the charging and
discharging curves into the lab report.
1. For all practical purposes, a capacitor is considered fully discharged (or fully charged)
after 5 time constants. What is the voltage across a discharging capacitor in a RC circuit
that has V₁ = 10V, and t = 5 t seconds? Show your work
2.
What is the purpose of finding t in a RC circuit?
3. In the virtual simulation, the light bulb is a nice visual indicator of the behavior of a
discharging series RC circuit. However, explain why is it easier to find C using a resistor
instead of a Light Bulb.
