How does a multipoint circuit differ from a point-to-point circuit? • A point-to-point configuration is so named because it goes from one point to another (e.g.‚ one computer to another computer). These circuits sometimes are called dedicated circuits because they are dedicated to the use of these two computers. • In a multipoint configuration (also called a shared circuit)‚ many computers are connected on the same circuit. This means that each must share the circuit with the others‚ much

Title: Resistors in Series and Parallel Date: 17/7/05 Aim: The aim of this experiment is to compare the predicted and actual resistance in a circuit of resistor combinations in series and in parallel. Background: A resistor is an electrical component/device that has electrical resistance. Resistors can be used in electric circuits for protection of components‚ voltage division or current control. In an ideal resistor the resistance remains constant regardless of the applied voltage or current

effectively operate and protect a motor. 1 MOTOR STARTING All motors must have a control device to start and stop the motor called a “motor controller”. Motor Controller A motor controller is the actual device that energizes and de-energizes the circuit to the motor so that it can start and stop. • Motor controllers may include some or all of the following motor control functions: S S starting‚ stopping‚ over-current protection‚ overload protection‚ reversing‚ speed changing‚ jogging‚ plugging‚ sequence

DIWALI LIGHTS The Basic Circuit [pic] FIGURE 1 As you can see in the above diagram that IC LM4017 will give 10 different O/P’s. Now here I have used this circuit for a 5 Channel Sequencer (The word sequencer seems very tough but the circuit is as simple as you can think). Looking at the Data Sheet of IC LM4017 we observe that we do not need any extra components to drive this IC (and that is what makes our CKT very compact). [pic] Now build 11 circuits as mentioned in FIGURE 1

Prelim have to wrk out open circuit potential diff between no light and light on. Increase in potential due to light being absorbed + find open circuit potential then add 0.5V to ocp that gives boundarys high end pottetnial is 0.5 added to OCP. Low end potential should be zero but taken further to allow easier read off. This is used as values on cyclic voltammetry. One light and one dark on all graphs. Short circuit value is where cv potential is zero Short circuit current is where cv potential
