PRELAB 1. For the circuit in Figure 8-1, use mesh analysis to calculate the mesh currents. Call your
currents IA, 113, and 15. Record these currents (magnitude and direction) in Table 8-2. 2. Having determined all mesh currents, calculate the current through (magnitude & direction)
and the voltage across (magnitude & polarity) for each resistor. Record these values in the
Tables 8-3 and 8-4 respectively. 3. Write and solve node voltage equations for the circuit of Figure 8-1, and then, solve for the
current through (magnitude and direction) and the voltage across (magnitude and polarity) for
each resistor. Record these values in Tables 8-3 and 8-4 respectively. 4. For the circuit of Figure 8-1 use superposition to calculate the current through and voltage
across R2 (the resistor of interest). It is not required to do calculations for any resistor other
than R2. Record the values in Tables 8-3 and 8-4 respectively. 5. Perform a computer simulation of the circuit using PSpice or Multisim, and use the results to
ﬁnd the current through (magnitude and direction) and the voltage across (magnitude and
polarity) for each resistor. Record these values in Tables 8-3 and 8-4. Create a screenshot of
the simulation showing the results, and include it in your prelab. 5V Figure 8-1 Circuit for testing
