Power electronics Mid-1 Objective exam 2011 1.When UJT is used for triggering an SCR‚ the wave shape of the voltage obtained from UJT firing circuit is a a) Sine wave (b) saw tooth wave (c)trapezoidal wave (d) Square wave 2. In a thyristor circuit‚ the angle of conduction can be changed by changing (a) anode Voltage (b) Anode Current (c) Forward Current rating (d)gate Current 3. Freewheeling diodes are mainly used for (a) Better utilization factor (b) di/dt protection

* Disconnect slow-moving products and focus on high margin‚ high volume products to max revenue not working cuz big customers buy these products * Use statistical forecasting package to predict demand and can lower inventory level (least squares regression) * Too many warehouse‚ need to reduce the amount to reduce inventory can only reduce the fixed cost‚ will rake longer time and cost more like transportation

Nearly all the children I work with in this group benefit from having hands on resources to help their understanding e.g. multi link and for counting to 100 a number square so that they can see the numbers. As I have worked with these children for a short while‚ I am not too sure‚ what they can and cannot achieve so there for I am aware of the boundaries as a teaching assistant‚ so I make sure that the children have

http://philcivilserviceexam.blogspot.com/ PROBLEM SOLVING 1. Miss Roxas bought 20 blouses for P1800 and marked them to sell at P110 each. After selling 16 pieces at this rate‚ she decided to sell the remaining blouses at a lower price. At what price may she sell each remaining blouse and still realize a gross profit of P360 on the 20 blouses? 1. P100 4. P115 2. P105 5. P120 3. P110 Solution: No. of Blouses Bought = 20 Original Price for 20 Blouses = 1800 Original Price Per Blouse = 1800 / 20 =

and feel as if an elementary student can easily make it into a museum just by doing what Clayton Hurt created. The one piece that I did not understand was the one below both of the pictures. It resembles butcher paper that was crumbled up into a square and spray painted by black spray paint. To some it could look very interesting but to others it can be just something anyone can do at their homes. When I felt the art work however‚ it felt metal but did not seem very heavy. It does create this

When used in stable mode‚ the 555 acts as a square wave oscillator whose clock rate is dependent on a time constant provided by two resistors and a capacitor. Many of the 555s weren’t providing a stable clock
