2 A BSTRACT Using Multisim construct a series circuit and test different voltage drops across the circuit and verify validity of KVL. I NTRODUCTION Using KVL and different equations and also Multisim I constructed a circuit to confirm the law and verify that it is correct. P ROCEDURES First I created the circuit using the multisim software. I used three resistors, a power supply, and a ground. I then used a multimeter to measure the voltage and the voltage drop across the three different resistors and when I moved the ground between three points on the circuit. Two examples are below along with data. 1. R ESULTS Measure the voltage across the power supply, V s = _12v_ 2. Measure the current flowing in the circuit, I T = __.084a_____ 3. Measure the voltage across each resistor. 4. Include a screen shot.

Voltage stays consistent along all parts of the circuit except where there is a voltage drop from a resistor, and also where the ground of the circuit is. Also, regardless of where the ground is, the voltage drop remains the same and so does the current throughout the circuit.
