my wrong there,i draw it wrong in orcad but yes,in the real test circuit the 33ohm resistor is in series with the load. and i remove r2 and r3 from the circuit to make sure all the current goes to the battery and to remove all other variables. when i turn on the adapter and measure the voltage of the battery,it goes up to 9.5v and then i turn off the adapter because the battery is rated at 8.4v only (dont have any goggles around).
what is wrong?
or i shouldnt remove r2 and r3 from the circuit?
this is the test circuit but without r2 and r3 and the value of r1 is 33ohm
*will try to build the circuit as you suggested this weekend and hook it up to my arduino and re measure everything
