Hello, I have a question about a formula I have used many times to figure out how high the current would be at a certain point in time
uH (micro Heneries) / Voltage = RiseTime ( microseconds) to 1 amp
I can clarify more if someone isn't sure what it means exactly.
But I have a question about this equation and the rise time of the current.
I know that when calculating the rise time, the first time constant is 63% of the total value. Since the current basically jumps to 63% then takes more and more time to reach full, Does this equation tell you the 1st time constant or the total overall value?
The reason I am asking is because if the equation tells you the overall value then that means that you could reach 63% of that total value much faster and if you just increased the voltage so that the 1st time constant (63%) is equal to that of the total current value at the lower voltage. Then once you have reached that value you can just stop trying to reach maximum since that is going to take much longer.
So does anyone know what that Equation tells you exactly, Is it the Total value or is it like just the 1st time constant? I believe it is the Total value that the current would reach in that amount of time, not the 1st time constant or 63% of it's total value.
Also I have attached a picture demonstrating what I am talking about.
You can see in the image that the voltage decreases rapidly then levels off.
You can't see the current, but the current is basically the reverse going up and then leveling off toward the top.
By the way, If anyone is interested in the program, just message me.
