resistor is color coded, or has a given value, how does the value from your plot compare to that value? Calculate the percent difference in each case and comment on the differences. IV. Questions - Ohm’s LawAre your observations consistent with Ohm’s law? V. Equipment and Procedure- Kirchhoff’s Laws A. Equipment Voltage source, DMM, resistors. B. Procedure Set up the circuits shown in Figure 2and Figure 3with resistors of known value. Measure the current in each resistor and the potential difference across it.
1.
For the series circuit measure the current at a, b, and c and the potential difference
between points ab, bc, etc.
2.
In
Figure
3
, the ammeter must be inserted in the circuit in the proper location or it will
measure the current for more than one resistor.
To measure the current
I
l
, the
ammeter must be inserted at
a
or
a'
.
To obtain the current
I
2
, the ammeter must be
inserted at
b
or
b'
.
If the ammeter is inserted at d, it will measure the current to both
R
2
and
R
3
.
VI. Results and Discussion- Kirchhoff’s LawsRecord tables of voltage, current, and resistance values in both the series and parallel cases. Compare the measured values of the currents in the series and parallel circuits to the theoretical values based on known values of the potential differences and resistors and verify Kirchhoff's Current and Voltage Laws. VII. Questions - Kirchhoff’s LawsAre your observations consistent with Kirchhoff’s Laws?
