Do electric power steering units use inverters? I’ve seen some commercial vehicle ePS unit’s talking about integrated inverters, but I was assuming ePS units operate a DCDC motor, so is there ever a need to convert to AC? I assume if it’s operating at a different voltage there may need a...
Hello, hoping to be pointed towards anything on the topic of power transmission selection based on current levels. I’m familiar with changing wire gauge size based on higher current, but at what point do different power transmission methods start to make commercial sense? For example when do bus...
is there a simple equation to use to find the average bearing stress in a slot in a plate due to a bolt loading?
I've seen the equation STRESS=F/A and for small holes A=dt (where d=bolt diameter and t=thickness of the plate) but how do you apply this stress equation to a bolt acting on a slot...
no application in particular...
got some projects i'm working on that require more and more electronics, thought i'd brush up on my knowledge. and experiementing and hands-on knowledge is the way I learn best. just trying to make a general testing setup for learning.
I see a flood of AC/DC converters out there but is there an off the shelf product that does a straight AC to DC conversion at the same voltage (over an AC input range between 0-120V). So I can plug this converter into a wall outlet at 120V AC and then plug something else into this converter...
Thanks LiteYear, I'll read over that.
I've been looking at Peukert's Law but have a feeling it didn't give me what I wanted.
Compositepro, let's say a NiCd. is there an empirical equation out there to give voltage for a continuous discharge to a resistor?
Thanks racookpa for the quick response...
1)1.2mA (assuming 1.2V and 1kohm)
1A) I don't have a final current I'm looking for an equation that will tell me the current at any moment in time
2) just from my experience that batteries die when used
3) looking for a theoretical solution
4) do you...
I'm having trouble finding an applicable equation to use...
Let's say I have a simple circuit with a voltage source and a resistor. I know the initial voltage of the battery and the resistance of the resistor, I want to know the current (or voltage) with respect to time.
what equation will...
is there a simple inexpensive electronic device that I can buy and put in series with an wall outlet that can produce a voltage from 0-120V by turning a dial or something simple. I'm thinking something simple like a dimmer switch, but I know those only vary voltage over a small range. Thanks for...
How could I calculate the minimum voltage required to light up a simple 60W tungsten incandescent light bulb, assuming that I have a wire and a variable voltage source?
I could set up an experiment and connect the bulb to the voltage source and slowly crank up the voltage from zero until I see...
I'm am trying to understand electronics by playing around with them, and I want to know the very simplest way of creating any periodically time varying current (AC)from a DC power source. I don't care about the shape or amplitude of the AC currnet as long as it has a periodic frequency...

Waross, by detecting do you mean a noticeable current is flowing thru it? What is defined by a working radio receiver? A metal pole? Does it need to be a closed circuit? Grounded? Etc?
yes...I dont want to build one i want an understanding of the physics behind it (which those forums didn't provide). I've seen prepackaged circuits with a lot of stuff in it but very little on the actual simple thoeries. I realy just want to know if I have a room full of radio waves and a metal...
maybe i didn't word my question clearly...Ive seen people make small circuits with a clock or light that is entirely powered by an antenna converting radio waves into a current. Im interested in how that happens on a very basic level, say I start with a room full of radio waves and a metal pole...
