Questions and Problems: 1. Describe the type of meter movement used in analog meters. The current in the circuit is used in basic meters to measure the voltage drop or current in the circuit. The current passes through the coils of wires‚ which is then magnetized. Inside the apparatus‚ there is also a permanent magnet which opposes the magnetic field of the magnetized coil of wire that is connected to the pointer therefore‚ as we see in meters‚ the pointer moves. There is also a spring connected

Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

The purpose of this lab is to determine the substance that are required in order for muscle to contract. We are experiencing this contraction by having three different solutions which contains their own disparate chemicals inside. Hypothesis: Solution A: 0.25% ATP solutions in distilled water; Base on muscle contraction mechanism which we know the force that generating cycle required is indeed of a lot of energy in the form of ATP‚ but there are additional solutions; KCl‚ MgCl2 which are needed

terminology Series Circuits Parallel Circuits Ohm’s Law and dc Circuits Simple Electrical Diagrams For single-source parallel networks‚ the source current (I ) is equal to the sum of the individual branch currents. s Is = I1 + I 2 For a parallel circuit‚ source current equals the sum of the branch currents. For a series circuit‚ the applied voltage equals the sum of the voltage drops. V V In this first example‚ we will calculate the amount of current (I) in a circuit‚ given values

ABSTRACT On the past two weeks‚ I have done an experiment on hydrostatics‚ or is also known as fluid statics (fluid at rest) within the fluid mechanics field of study. This condition explains that in a stable condition‚ the fluid is at rest. The use of fluid in doing work is known as hydraulics‚ and the science of fluid in motion is known as fluid dynamics. INTRODUCTION The natural nature of fluids are they cannot remain stationary under the application of shear stress. However‚ fluid

Planarian Lab Report Hanna Klein Bishop Fenwick High School Planarian Lab Report Introduction Planarian worms are free-living flatworms that are not parasitic. Planarians have a three-cavity digestive system. Planarians are usually either carnivorous or scavengers. Planarians may eat other living‚ as well as dead‚ invertebrates‚ detritus or decaying organic matter. Planarians do not realize that are eating a lot‚ and can over eat resulting in death. Most planarians are freshwater forms that can

Abstract : A DC power supply is very important in our day to day life. We use it to charge or operate our DC components like charger light‚ cell phone battery charger etc. It’s nothing but a AC to DC converter. Keywords: 5V DC power supply‚ rectifier‚ diode‚ filter‚ capacitor‚ zener diode‚ voltage regulator‚ signal‚ waveshape. 1. Introduction I’m designing a 5V DC power supply. Here I’m basically designing a AC to DC converter. To convert the AC to DC‚ I’m using components like full wave bridge

Measurements of Capacitance and Inductance Purpose: To use equipment and techniques to determine the structure of a hidden series RLC circuit and to measure the values of the various components in that circuit. Theory: To see how an RLC circuit works‚ consider the circuit in Figure 1 with the capacitor initially charged. Fig. 1 RLC Circuit Since there is a conducting wire connecting the negative side of the capacitor to the positive‚ a current will begin to flow in the counterclockwise

Laboratory Report on the Reaction of Flames Towards Medals  Introduction The purpose of the flame lab was to identify a set of flame-test color standards for selected metal ions‚ relate the colors of a flame test to the behavior of excited electrons in a metal ion‚ observe spectral lines using diffraction grating‚ and to identify an unknown metal ion by using a flame test. My hypothesis for the lab was that most of the flames when sprayed with a solution will be a orange-red color. The
