Electrical Engineering Questions & Answers

  Sketch the circuit needed to implement the counter

a binary pulse counter can be constructed by inter connecting t-typeflip-flops in an appropriate manner. assume it is desired toconstruct a counter which can count up to 100 subscript 10. A) how many flip flops are required

  Plot the voltage that is displayed on the oscilloscope

While it's very reliable, it can only supply a maximum power of 60W. If someone tries to draw more than 60W, the output current is reduced to zero and stays there until someone presses a "reset" button on the supply.
