How to Avoid Emitter Resistors in Parallel BJTs Although the use of emitter current limiter resistors looks good and technically correct, a simpler and a smarter approach could be to mount the BJTs over a common heatsink with a lot of heatsink paste applied to their contact surfaces. ...
If two resistors of R1 and R2 ohms are connected in parallel in an electric circuit to make an R ohm resistor, the value of R can be found from the equation, 1R=1R1+1R2 If R1 is decreasing at the rate of 1 ohm/sec and R2 i increasing at the rate of 0.5 ohm/sec, at what ...
