circuits. Then‚ we were to take out the needed materials and parts of the circuits to start the lab. We then build a series circuit‚ with three resistors‚ a switch‚ a power source‚ and a few spacers in between. Next‚ we were to configure the multimeter as a voltmeter and an ammeter‚ to measure the potential differences and currents of the resistors in the series circuit. Later‚ we were to follow the same procedure with a parallel circuit. The biggest error that was presented in this lab was

Measuring the Resistivity of Copper Wire of Different Lengths In this report I will be writing about the experiment I will conduct on copper wire of different lengths. The dependent variable I will be measuring is the resistance of the Copper wire. To do this experiment‚ one needs to obtain measurements with a high degree of accuracy‚ taking care of the equipment they use and measuring each value to a certain degree of accuracy for all results. The problem with measuring the resistivity of Copper

opposition to the flow of current‚ and capacitive reactance is the opposition to the flow of charge. The tools we used for this experiment a pair of resistors‚ an inductor‚ a capacitor‚ dual channel oscilloscope‚ audio oscillator‚ and a digital multimeter. Using the oscilloscope we where able to measure the devises easily. Using the audio oscillator too change our setting to the wright context we measured the Vrms of our circuits. Using the Vrms we were able to find all of our unknowns using equations

BASIC DIODE ELECTRONICS INTRODUCTION TO DIODES The p-n Junction The p-n junction is a homojunction between a p-type and an n-type semiconductor. It acts as a diode‚ which can serve in electronics as a rectifier‚ logic gate‚ voltage regulator (Zener diode)‚ switching or tuner (varactor diode); and in optoelectronics as a light-emitting diode (LED)‚ laser diode‚ photodetector‚ or solar cell. In a relatively simplified view of semiconductor materials‚ we can envision a semiconductor as having two

There are numerous sets of instructions for making lemon batteries and for obtaining components such as light-emitting diodes (LEDs)‚ electrical meters (multimeters)‚ and zinc-coated (galvanized) nails and screws.[2][3] Commercial "potato clock" science kits include electrodes and a low-voltage digital clock. After one cell is assembled‚ a multimeter can be used to measure the voltage or the electrical current from the voltaic cell; a typical voltage is 0.9 V with lemons. Currents are more variable

coefficient of resistivity () is a measure how temperature affects resistivity. We cannot measure resistivity directly- however by measuring the resistance of a wire with an ohmmeter‚ we can calculate the resistivity.
