As far as I know, the collector current depends on the base current by the equation IC = β × IB. However, the voltage drop across the collector resistor depends on the collector current. So how did the collector resistor limit the collector current?
I wanted to know the content of W register and content of the adress location 12H in pic 16f84 micrcontroller.
I have write this simple code
RES_VECT CODE 0x0000
GOTO START
MAIN_PROG CODE
START
MAIN
MOVLW b'11';// w contains 3
MOVWF 12H ...
I can’t understand How the W register is incremented every time with the value 22H since the content of 12H register is 0 and every time we add it with 0 and stores the result back in the w register it becomes 0+22H = 22H. I think the result will be a fixed value i.e 22H
in line 4 ADDWF 12H, W...
Hello guys i just started to learn assembly language for pic micrcontroller.in this text i think The line written twice
A B F
0 0 0
0 0 0
is superfluous. What do you think? Why it is written twice?
OK. I am having difficulty understanding the meaning of these lines
1)Why it is called a saturated transistor switch??
2)"Without squandering excessive power......................."
In this line where do we squander excessive power?? is it on the input side??
3) Why this analog switch can...

But I think, in that case, the whole short circuit current flows through the voltage regulators.
Previously I thought it was short circuit protection for the voltage...
Hi, guys I want to know what is the purpose of the transistor Q2 in this circuit.
I think it acts as a bridge between Q1 and the voltage regulator and balances the current between them. If the droop across RSC is higher then Q2 starts conducting and thus cuts the input current to the transistor...
