ECT 122
Week 4 iLab 3
1.Calculate
the current in each branch of the parallel circuit below.
2.Download
the Multisim file “Parallel1” from Doc Sharing, Week 4. Run the simulation and
verify the simulated results are the same as the calculated values. Were the
values the same? (YES/NO.) If no, why?
3.Calculate
the total power dissipated in the circuit by using the total voltage and
current. Then calculate the power dissipated in each resistor and verify that
the sum of the power dissipated in each resistor equals the total power
dissipated.
4.Construct
the circuit above on the breadboard. Connect the circuit’s input to the
variable positive supply. Set the supply to +8V. Use the handheld DMM to adjust
the supply to +8 V. Using the handheld DMM, measure the currents below.
Remember, to measure current, the handheld DMM must be in series with the
resistor. Have the professor verify the circuit before
applying power.
