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

: 08/05/2013 LECTURER : MS. FATIN HANA NANING Objective To verify Kirchhoff’s Laws by comparing voltages obtained from a real circuit to those predicted by Kirchhoff’s Law. Theory Ohm’s Law describes the relationship between current‚ voltage‚ and resistance in simple circuits. Many circuits are more complex and cannot be solved with Ohm’s Law. These circuits have many power sources and branches which would make

LM317‚ NCV317 1.5 A Adjustable Output‚ Positive Voltage Regulator The LM317 is an adjustable 3−terminal positive voltage regulator capable of supplying in excess of 1.5 A over an output voltage range of 1.2 V to 37 V. This voltage regulator is exceptionally easy to use and requires only two external resistors to set the output voltage. Further‚ it employs internal current limiting‚ thermal shutdown and safe area compensation‚ making it essentially blow−out proof. The LM317 serves a wide variety

the algebraic sum of all currents in a network of conductors meeting at a point is zero (Eq 1). (Eq 1) Kirchhoff’s Second Law‚ also called Kirchhoff’s Voltage Law (KVL)‚ states that the sum of the voltage gains in any closed loop is equivalent to the sum of the voltage drops in that loop. In other words‚ the algebraic sum of the voltages (Vk) in a closed loop is equal to zero (Eq 2). (Eq 2) Equations (1) and (2) are interrelated‚ and this can be demonstrated through modeling a basic electrical

Introduction FIGURE 1 : N-Channel JFET The Junction Field Effect Transistor (JFET) is a three terminal device that consists of drain‚ source‚ and gate. The JFET is a voltage-controlled‚ constant-current device and a unipolar device. For this experiment‚ we used the JFET Self-bias circuit which in particular we use the n-channel. This kind of circuit is simple yet effective and is the most common biasing method for JFETs. The important thing to know is that the gate is essentially
