to be very dangerous if circuits are not properly protected. The major fault that appears in electrical network or equipment is termed as short circuit. In short circuit‚ the supply phase and neutral or earth is short circuited accidentally due to foreign metallic substance coming in contact with phase & neutral or earth or due to overload thereby damaging the insulation resulting in short circuit i.e. directly connected resulting in heavy current flow called "short circuit current". This high current

loops of op-amp amplifier circuits‚ we can cause the output to respond to changes in the input voltage over time. Drawing their names from their respective calculus functions‚ the integrator produces a voltage output proportional to the product of the input voltage and time; and the differentiator produces a voltage output proportional to the input voltage ’s rate of change. The objective of this experiment is to get familiarized with integrator and differentiator circuits Theory and Methodology:

resistor is ohmic or non ohmic Background Information An electric circuit is formed when a conductive path is created to allow free electrons to continuously move. This continuous movement of free electrons through the conductors of a circuit is called a current‚ and it is often referred to in terms of "flow‚" just like the flow of a liquid through a hollow pipe. The force motivating electrons to "flow" in a circuit is called voltage. Voltage is a specific measure of potential energy that

solution of complicated networks (particularly‚ electronic networks) quite quick and easy. The Thevenin’s theorem‚ as applied to d.c. circuits‚ may be stated as under: The current flowing through a load resistance RL connected across any two terminals A and B of a linear‚ active bilateral network is given by VOC || (Ri + RL) where VOC is the open-circuit voltage (i.e. voltage across the two terminals when RL is removed) and Ri is the internal resistance of the network as viewed back into the

window foil that "breaks" a circuit as the glass is broken. It is an alarm that is triggered when the protective circuit is opened. Circuit Operation:- The circuit consist of a n-p-n transistor‚ an alarm working on 6V DC and a SCR (Silicon Controlled Rectifier). The transistor is biased in voltage divider mode. the out put is taken from the emitter which is fed to the SCR gate. The transistor biasing circuit acts as a voltage follower to the SCR. When the protective circuit is closed‚ the transistor
