AC/DC was formed in December‚ 1973‚ in Australia‚ by guitarist Malcolm Young‚ whom had just left his last band‚ Velvet Underground. He saw first hand all the benefits that came with being a rock star‚ as his older brother‚ George Young‚ reach the big time as a member of the popular 1960s band‚ the Easybeats. He very much wanted to follow in George’s footsteps. Malcolm also could see that his younger brother‚ Angus‚ was a very talented guitar player‚ even if he was only 15 years old‚ and picked him

distances. Around that same time‚ Nikola Tesla was diligently trying to master the alternate current (AC) motors and generators even though he was discouraged from doing so. After proving his invention to be a practical solution for this problem‚ George Westinghouse purchased Tesla’s patents and opened his first power plant that supplied AC electricity to parts of Massachusetts and New York. With AC being able to distribute over long distances‚ this was the obvious choice and is now used all over the

Kirchhoff’s Law Kirchhoff’s current law (KCL) imposes constraints on the currents in the branches that are attached to each node of a circuit. In simplest terms‚ KCL states that the sum of the currents that are entering a given node must equal the sum of the currents that are leaving the node. Thus‚ the set of currents in branches attached to a given node can be partitioned into two groups whose orientation is away from (into) the node. The two groups must contain the same net current. In general

1. Motors use the effect of forces on current-carrying conductors in magnetic fields Discuss the effect on the magnitude of the force on a current-carrying conductor of variations in: The strength of the magnetic field in which it is located • The magnitude of the force is proportional to the magnetic field strength. Thus‚ an increase in magnetic field strength will cause an increase in the force on the wire and a decrease in magnetic field strength will cause a decrease in force on the

A bibliography is a list of books‚ scholarly articles‚ and other sources you use when researching a topic and writing a paper. The bibliography will appear at the end of your paper. The bibliography is sometimes called Works Cited or Works Consulted. Bibliography entries must be written in a very specific format‚ but that format will depend you the particular style of writing you use. Your teacher will tell you which style to use‚ and for most school papers these will be either MLA‚ APA‚ or Turabian

Types of DC Motors and DC Generators MOTORS – convert electrical energy to mechanical energy Motors and generators are the most frequent used electrical machines. ❖ Generators action can take place when and only when‚ there is a relative motion between conducting wires and magnetic lines of force. ❖ Electric motor is in operation when it is supplied with electrical energy and develops torque‚ that is‚ a tendency to produce rotation. ❖ In DC generator‚ the armature winding is mechanically

design a 3-bit even parity generator that can detect a one-bit error in a message and draw the CMOS layout in L-Edit‚ which can then be simulated using PSPICE. Abstract: An even parity bit generator generates an output of 0 if the number of 1’s in the input sequence is even and 1 if the number of 1’s in the input sequence is odd. The checker circuit gives an output of 0 if there is no error in the parity bit generated. Thus it basically checks to see if the parity bit generator is error free or not.
