Interpretation of Results As observed by the group in a normal diode circuit placed in a forward bias generates a sinusoidal output wave. In order to trim the output waves‚ that are a sinusoidal wave‚ to be generated‚ a clipper circuit was made with the use of diodes. The limiting level of a clipper circuit is the barrier potential of the diode in use. A diode clipper that trims down the positive half cycle input of a wave signal is as positive limiter. The output signal will retain the original

voltage must be converted into a DC voltage with the right value and degree of stabilization. Figures 1 and 2 show the simplest rectifier circuits. In these basic configurations the peak voltage across the load is equal to the peak value of the AC voltage supplied by the transformer’s secondary winding. For most applications the output ripple produced by these circuits is too high. However‚ for some applications - driving small motors or lamps‚ for example - they are satisfactory. If a filter capacitor

Question 1(a) Power A 100a Distribution Board will be used to power Block L. A ring circuit will provide power to the substation room and Generator/switch room (labelled Sockets‚ Generator/Switchroom). It will be protected by a 32A BS EN 60898 type C RCBO. The RCBO type C is used as equipment could either be plugged in from outside or attached to an inductive load. Another ring circuit will provide power for the workshop and restroom (labelled Sockets‚ Workshop/Restroom)‚ this will also be protected

that any resistive circuit or network‚ no matter how complex‚ can be represented as a voltage source in series with a source resistance. It is used to simplify the load analysis of series-parallel circuits. 2. What is VTH ? How is it measured? Thevenin voltage. In a series-parallel circuit is the voltage present at the output terminals of the circuit when the load is removed. Even though it has a new name VTH is nothing more than the no-load output voltage VNL for the circuit. Vth can be found

node voltages of both planar and non-planar circuits. Nodal equations are usually formed by applying Kirchoff’s Current Law to the nodes with unknown voltages‚ whereas equations based on Kirchoff’s Voltage Law are used to form the mesh equations. In order to apply nodal analysis to a circuit‚ the first step is to select a reference node or datum node and then assign a voltage at each of the other nodes with respect to the reference node. In a circuit with dc sources‚ the node that has the lowest
