Introduction: Today’s laboratory experiment consisted in learning how to use  Kirchhoff’s rules for circuits to find the resistance, voltage, and current everywhere  around the circuit. Our experiment consisted in making a simple circuit with five  resistors; two pairs of resistors were connected in parallel, and those two pairs along  with a single resistor were connected in series. We measured with a multimeter the  resistance across each resistor, with a voltmeter the voltage across each resistor, and  with an ammeter the current through each resistor. Our analysis consisted in solving the  values of the currents through each resistor using kirchhoff’s two rules and comparing

Unformatted text preview: our calculated values with our experimental measured values. Analysis is in following pages. Conclusion: In this experiment I learned the concepts behind both of kirchhoff’s rules and how to use them to find unknowns in a simple circuit. I was able to prove experimentally that kirchhoff’s rules are valid. Kirchhoff’s first rule says that the sum of the current going into a junction must equal the sum of the current leaving the junction, just like water in pipes. The second rule states that the sum of the change in voltage around a closed loop must equal zero. I was able to see a different way, in which many cases may be much easier, to solve for unknowns than using Ohm’s Law....
