& Designing Theory: Resistance is a property of any object or substance to resist or oppose the flow of an electrical current. The quantity of resistance in an electric circuit determines the amount of current flowing in the circuit for any given voltage applied to the circuit. This is according to Ohm’s law. The unit of resistance is the Ohm which has the Greek letter ’Omega (Ω)’. By default‚ that is‚ for electrical calculations‚ the inverse of Resistance is obtained and this is known as conductance

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
