Unformatted text preview: Prclab 1 First, acquire all the needed material to determine Vac and RINT (battery, multimeter,
resistor, and circuit wires). In order to determine the value of VOC, you should connect the
multimeter in series “(HP the battery to read its voltage under no load (i.e. simply touch the ends talk ,
of the battery). FQIOrthennore, to determine Rmconnect the battery to a re51stor of known value , . , :0 ll! ‘ .
and observe what the voltage is under that load using the multimeter 1n saés once again. From
the values that you ﬁnd, you can solve for the current using Ohm’s Law. Then use voltage division to determine RM. Value of known external resistor:
P = V2 I R 0.25 W = (9 V)2 /R R = 324 n \/ J" ...
