Two resistors a and b are connected in parallel to a 12-v battery. resistor A has 9 V across it. which resistor has the least resistance? A + ar + ar2 + .......
the sum of the first two terms is 24 and the sum to infinity is 27. Show that r = +,- 3? Physics help!! The magnetic field in a solenoid that has 230 loops and a length of 18 cm is 9.4 ×10−5T. What is the current in the solenoid? If i am discharging a capacitor of tension Uc in a resistance R,in my book they say that Uc+Ri=0
can you say why it is not Uc=Ri? What kind of spider is this? This was found in a central New Jersey basement.?
