ok
With the use of resistor is ok but it is lossy & not workable or i can say not preferable.
even i have also find same issue as tony mention in his reply.
Transistor have their safe operating area.
one thought i have can we use MOSFET ?
because MOSFET can easily come with higher current.
If...
Dear Klaus,
Thanks for the response & quires.
A High power 100V, 20A DC source is available. I need to charge 30mF, 250 VDC capacitor with 10A contact current circuit. Here source is 100V so capacitor is charged up to 100 VDC only. This capacitance 30mF is fixed.
Charging current 10A is not...
I have big capacitor of 30mF, 250 VDC & I want it to charge at 100 VDC with 10A constant current.
What i feel is that it possible with the PNP transistor. With the use of resistor i can do it but for that requirement of resistor is higher & apart from that losses across resistor is higher.
Hi,
I want to know the actual circuit which generate the signal 1 attached by you.
So that i can help you to convert signal1 into signal 2.
If you can't attached here mail me on pcb_vap@yahoo.com

Hi
First go through the following link
https://forums.ni.com/t5/Circuit-Design-Suite-Multisim/8051-beginner/td-p/808968
it will help you in simulation.
Try to simulate the simple LED Blinking Code. It will help you to simulate your circuit also.
I checked your circuit. For complete check I...
Hi,
I am BE electronics engineer from Gujarat. I want to join this team.
I have good knowledge of PCB Design & Analog Circuit design.
I have experience on OrCAD PCB Design from schematic entry to gerber release & gerber file checking (for FPGA & CPLD also). Also experience in electronics...
Hello,
First of all you have to search the multisim tutorial available on the internet.
you can find easily
read it carefully
you can easily get the idea that how to run any circuitry.
Then if any problem pls tell.
Thanks,
Vimal Patel
Dear atripathi,
if you have any tutorial regarding noise analysis, Kindly send me.
Mail ID: patelvimal20@yahoo.com
it will be great help if I will any tutorial.
Thanks for your replay,
Vimal Patel
Definately, Resistor calculation is there.
Before that you have to take care of some important things:
Number of LEDs
Your source rating
the most important thing is that you told that you are planning for vehicale light so that you have to see the area also.
Please let me know the number of LED...
