Potential Mapping Lab
1. The resistance can be found by manipulating Ohms law to solve for R. Ohms law is
V=IR therefore, R = V/I. For the circle, the voltage was 6 V and the current was .2 mA.
R= 6/ .2 = 30 1 k. F

1. Start with Ohms law, V=IR

V(t)= R e R

V(t)= V o e RC .
b. You would have to wait until t equals the time constant, RC. This would make the
exponent -1, meaning that

Experiment 3: Adding Resistors
1. So, basically Req/total = R1 +R2. We found each individual resistance and in series and we then
able to calculate the Req/total (simple addition). You can also find

1. The reason the total resistance is the two resistance s added up is because from Ohms law V=IR
so when the current has to go through two resistors the current is resisted twice. So through
that knowledge t

1. The measured value for the period was T = 1.0 0.1 ms. This is consistent with the
expected period. The measured value for the frequency, as calculated using the equation:

Adding Resistors Lab (3)
1. We know that when two resistors are connected in series, the charge that flows across
each is equal to the total charge while the total voltage is equal to the individual voltag
