law is his voltage law. Kirchhoff’s Voltage Law (KVL) states that around any loop in a circuit‚ the voltage rises must equal the voltage drops. The next law that Kirchhoff introduced was his current law. Kirchhoff’s Current Law (KCL) states that the total current entering a junction must equal the total current leaving the junction. These laws‚ however‚ cannot be proven or tested without the aid of a multimeter. A multimeter is an instrument designed to measure electric current‚ voltage‚ and usually

CHAPTER 1 INTRODUCTION Now-a-days every institution needs automation. As a part of college automation‚ we have decided to do a project “voice interactive system for college automation”. Our project allows the user to know the student’s attendance and marks quickly through the telephone line without the intention of the college authority. In the hardware side embedded system has been used. The microcontroller controls the whole

Battery Desulfator Errata In my battery desulfator article on page 84 of HP77‚ the value for C2 should have been 0.0022 ìF‚ not 0.022 ìF. My mistake. I have put up a Web page that will give more details to help you build and use the desulfator circuit. I will place updates there‚ and will add a guestbook soon to allow comments and questions to be posted. I encourage a group effort in this‚ since I don’t have all the answers. Thanks.

Cities September 29‚ 2014 Introduction We measured the resistance per foot of a wire using setups of both two and four test leads in tandem with a digital voltmeter (DVM) and compared their accuracy. While resistance can be determined by measuring voltage and current separately‚ it can also be measured more simply and directly using the resistance measuring feature available to some digital voltmeters‚ such as the Agilent 34401A we employ here. Plugging two test leads into the DVM and placing them

velocity of the electron beam will affect the amount of deflection the electron beam experiences. We modeled the situation with a Cathode Ray Tube (CRT). Due to the known equation for the deflection of the beam‚ we predicted that the higher the voltage‚ the greater the deflection. Prediction: To begin making predictions for this experiment‚ we first made a diagram of what exactly our situation is‚ and how we can calculate the information we are looking to find‚ which is how the different

Study about Ohm’s Law: • To verify Ohm’s Law by calculating voltage‚ current and resistance based on different views of Ohm’s law as well as measuring those values to compare the theoretical results with the actual results. • To verify the relationships of R-I‚ V-I and R-V given ohm’s law by increasing one parameter while holding the other parameter constant‚ then measuring and calculating equivalent results of the third parameter. What is Ohm’s Law: Ohm’s Law is made from 3 mathematical equations
