Measurements:
(d)) Turn on the 12-V supply of Fig. 12.2, measure the voltage V₁, and record in
Table 12.3. Using the measured value of R₁, calculate the current I, and record in Table 12.3.
Calculation:
and 1(c)?
Determining RT
((e)) Determine Rah by constructing the network of Fig. 12.4 and measuring the re-
sistance between points a-a' with R, removed. Record in Table 12.1.
