Laboratory Title: Analysis of a DC Parallel Circuit using Simulation and Actual Construction

Submittal Date: Click here to enter a date.

Objectives:

1. To construct a parallel circuit correctly and measure its equivalent resistance.

    

2. To predict and verify electrical characteristics of a parallel circuit using Ohm’s Law and Kirchhoff’s Current Law.

    

3. Determine the various branch currents in the parallel circuit using the current divider rule. Measure and verify the same using the simulation. Use these values to also prove that the power delivered by the source is equal to the sum total of power dissipated by all the resistors in the circuit.

Questions:

1. Did you prove Kirchhoff’s Current Law to be true for a parallel circuit?  

  2. Explain how you proved Kirchhoff’s Current Law.

  3. How much power did this circuit dissipate?  

 4. What would happen to the current I₅ if one of the resistors, like R_4, is SHORT or OPEN circuited by chance? Will the current, compared to the original value:

  5. Expressing current and power dissipations in engineering units
