Abstract
In this lab, we investigated Kirchhoff’s rules and how to use them to calculate the
currents in a multiloop circuit. By using a voltmeter and ammeter, the current running through
the loop is measured. First, the total voltage is adjusted to 8.00 volts. The currents are measured
again from I1, I2, I3, I4, and I5. Even with high errors, there are similarly calculated currents
compared to experimental results. The highest percent error in Part I was 33%, and the highest
percent error in Part II was 36%. Other results concluded that Kirchhoff’s Rules are shown in
this Lab. Theory
