Emmanuella Dorvil ECE 11 lab Section 32 Ohm’s Law and DC Series Circuits Objective: The objective of this lab was to calculate the dc voltage and current across resistors in DC series circuits. Also to calculate the power supplied using the voltage and current measured. Background: To calculate the Ohm’s law must be used [I = V/R] (eq. 1) To calculate the power supplied the equation [P = IV] (eq. 2) To find percent error use abs(E-O/E)*100% {E= expected(nominal) O= observed(measured) Materials: A DMM Resistors Banana mini-grabber Bread board DC power supply Procedure: 1. Using the bread board construct the directed circuits in a series using R3, R4, R6, and R7. 2. Use the mini- grabber and connect the respective ends to the DMM and the other

Using the mini-grabber connect the circuit to the DMM and the DC power circuit. (Make sure that this is done in series with the circuit). 4. Calculate the power supplied to the resistors using eq. 2. Conclusion: For the table results of exercise 1-3 the percent error for the power supplied through the circuit • R3 = approx. 21% (ex. 1) • R4 = approx. 20% (ex. 1) • R6 = approx. 73% (ex. 2) • R7 = approx. 73% (ex. 2) • R4 = approx. 28% (ex. 3) • R6 = approx. 36% (ex. 3) • R7 = approx. 37% (ex. 3)...
