2 Series Circuits
Construct the circuit shown in Figure LT1-2-1.
Figure LT1-2-1
Compute (do not measure) the current in the circuit:
Table LT1-2-3
Table LT1-2-2
V43
R42
Table LT1-2-1
V31
Measure the voltages listed in Table LT1-2-3. The subscripts refer to the UTS Black Box 1 terminals. For example, 𝑉43 is the voltage between the terminals 4 (positive) and 3 (negative).
Table LT1-2-4
R31
Measure the resistance between UTS Black Box 1 terminals 4 and 2, ensuring that the black lead of the DMM goes to terminal 2. Enter your measured value in Table LT1-2-1.
Show Tables LT1-2-1 through to LT1-2-4 to a Lab Tutor.
Verify that your measurements satisfy KVL.
Assuming that the circuit is a series resistive circuit, and using only your measured results, determine the resistance between UTS Black Box 1 terminals 3 and 1:
