| Resistance and Electric Circuits | Lab 5 | | | The goal of the “Resistance and Electric Circuit” Lab was to determine the resistivity of a conducting wire given two known resistors. The main property of resistivity is that it represents how easily electrons can flow through a material. A Galvanometer is used to measure the current of the circuit and the Wheatstone Bridge is used to measure the resistances and determine the unknown resistance. This experiment also relates Ohm’s Law

Introduction - Electric circuit theory is one of the fundamental theories upon which all branches of electrical engineering are built. - Many branches of electrical engineering‚ such as power‚ electric machines‚ control‚ electronics‚ communications‚ and instrumentation‚ are based on electric circuit theory. - In electrical engineering‚ we are often interested in transferring energy from one point to another. - To do this requires an interconnection of electrical devices. - Such interconnection is

Experiment 3: Oscillators and timers Introduction The NE555 chip which operates at 5v‚ utilizes two comparators for temperature stability. This chip is capable of producing oscillations. It is made up of 8 pins and its oscillation mode is controlled by two resistors and a capacitor. Each pin is set to perform a function. Pin 1 serves as ground. Pin 2 is the trigger - the input to the lower comparator which sets the latch that causes output to go high. Pin 3 serves as the output.

Alternating Current RC and LRC Circuits Lab 7 November 12‚ 1012 109989- 5:30 PM Abstract Within this experiment we recorded that the theoretical capacitance of 0.470 is accurate with the capacitor from box C. The LRC circuit is proven to have a voltage accurate with the measured generator voltage because the largest percentage of error ‚ 0.55 % error‚ is much lower than 5% error. Summary The idea of the alternating current RC and LRC circuits lab is to record the value

In Unit 5 Activity 2 we were asked to predict and then find the brightness and flow rate of a closed circuit with a three cell battery pack‚ a long bulb‚ a capacitor parallel to the long bulb‚ and a round bulb. I originally predicted that the round bulb would be brighter when the circuit was first closed and when the circuit reached a steady state‚ and that the wire between the round bulb and the negative side of the battery would have a higher flow rate than the other wires. However‚ in the steady
