I am not beeing rude if I say what is true, but you are insulting me with false accusations.
forum is the place to discus topics, I newer force noone to spent their spare time, but I expect if that someone do post an answer that it would be of any sense, related to my question, otherwise that...
for sure you just quickly read my post, not even looking the diagrams. you are also beeing rude explainimg me what a ground is as i am a noob.
if you looked the diagram and read my post all your answers be answered and you will realise they are stupid.
you did not even give one logic thing in...
Hi
I have 2007 Renault Master in which wipers intermittent function does not work. other functions low and high speed works as well as 3 wipes if you spray watter.
I found some diagrams for this car (look below) and as fas as I understand the wiring of 5wire wiper motor, low and high speed are...
both speakers are from a kit with 5" main speaker, 2" tweeter and switch which is corroded. both are 4ohm, 5" is rated 75w rms, tweeter doesnt have that only 3-15khz.
in my local estore only 10 and 22 and 47 uf bipolars are awailable.
the diagram is just to show wiring, in my case I have car speakers, both are 4 ohm. So what value capacitor should I choose?
My tweeter freq says 3-15kHz. They say you should double the freq. Should I gove then with round 20 Uf? In my store bipolar comes as 22 uF. Will that be fine?
I also read...
Hi,
need help with connectin a tweeter to my car stereo without switch.
Here is a diagram, is it ok?
equation for capacitor value should be:
C=1/(2Pi*f*Z)
but this does not corelate with online chart
also it says contrary to the chart most tweeter capacitors are 500uF to cut bass freq...
Hi,
on internet I found different diagrams how to connect 4x4 matrix keyboard to a microcontroller.
this are the 4 different diagrams I found.
1st diagrams using ADC and voltage divider is understood 100%
2nd diagram with no resistors I thin is false since having no sink resistors on the...
Sorry my bad, I meat ohm.
so for feats I can use Rds(on) resistance when it is fully open and this resistance increases if it is not fully open but then also current decreases so P=I^2*Rds is sure enough equation to determine heat generation.
what about BJTs. Why 0.7 voltage drop? Does it...
For FETs they say P=I^2*Rds(on) and for BJTs they say P=voltage drop * I
For FETs Rds(on) is let's say 100mA and with current of 10A FET will generate 10W. TO220 housing has round 60C/W so with no heat sink it will quickly pass max operating temperature.
For BJT voltage drop should be 0.7V so...
Sorry if I am getting anoying but I really don't understand why I need those resistors?
I thought that 10k resistor that leads 12V to gate of dual MOSFET and to the colector of NPN acts as current limiter for both MOSFET and NPN.
Do I miss something about working of MOSFETS?
Only logic answer...
So did you have this circuit in mind? 12V to the gate of P MOSFET and NPN draining the gate of mosfet. How will NPN behave with PWM? Will it be proportional to the duty cycle or not.
Bellow is my circuit design. I am using dual p channel mosfet (FDS4935BZ) to dimm two H7 bulbs using PIC PWM. Since bulbs are connected to the ground in the headlight itself I can only use P channel mosfet. Since P channel mosfet is on when 0V is on the gate I am also using third P channel...
in prctise electricity is wery complex, I really do not understand now how this works but no matter. I have still some question regarding IT grounding.
In shematics there are 4 wires (L1, L2, L3, N), but under description they say there's no neutral and under schematics phases that go trough...
I am no expert only learning and trying to understand. What in case a tree touches those wires or one of the wire fell to the ground. Will then any current be carriing trough ground?
And sub question, why TN grounding system (residental block buildings) don't use RCD? I understand that having...
