Re: Question about a PCB
As Keith said, it is supposed to be there. But if you want to remove it use some kind of solvents (heat it so that the ink peels off or solvents like Acetone or nitro if it is a laser ink)...
I too agree with aryajur.... voltage divider output will change when you load current changes........... so it is better to find a transformer.......... Another way is that find two transformers one having a value of each output...........
Now if the above are not applicable......... Use the...
The formating means you are giving a new format to the system...... I think the operating system warned you about losing your data before you put the format. If you have done quick format, (deleting only the index entires of each file and leave the rest of the data same) you have fairly good...
The below link has fairly good amount of explanations of what causing the transformer over heating and about the power consideration. Paying a visit to the site will be helpful.
Practical considerations : TRANSFORMERS
Yes..........And the supplied amp will differ upon the device being controlled which is the coin box...... that is right
But 5A is very large current. So you usually don't require that much current.The 5A providing battery is also costly...... as I said earlier if you want you can go for lower...
question 1
Actually Yes, But since the current sources are not readily available, we use the voltage sources........ The rating 12v 5A means the switching is occured at 12V
and it can carry 5A of current safely........
Question 2
Actually it is ohms law, but instead of R (resistance) you...
In order to avoid confusion I have rotated the file, named the parts and A brief explanation is given below.
First, the abrrevated terms
T1= Transistor 1 (npn)
NC= Normally Closed Point
NO = Normally Open Point
Common pnt = Common Point
GND = Ground
Hope that clears the first part...... Now...
As 104 stands for .1 uF
I think 221 stands for .22nF
16V is indicating It is a 16 volt capacitor......
Hope this is helps in your search> Usually 3 value capacitors are calculated like that don't know weather it will be applicable for this
