It’s!hard!to!see,!but!the!voltage!
reading!on!the!power!supply!was!
11.93!after!calibrating!to!the!

8. Now,!construct!the!circuit!that!is!shown!by!the!schematic!of!figure!6.!Place!one!leg!of!the!
220Ω!resistor!into!the!(+)!rail!and!the!other!leg!into!one!of!the!inner!holes!on!the!board.!
Now,!place!one!leg!of!the!470Ω!resistor!in!one!of!the!holes!immediately!adjacent!to!the!hole!
on!the!inner!board!used!for!the!220Ω!resistor,!making!sure!it!is!the!same!numbered!hole,!
and!the!other!leg!into!the!(K)!rail.!
!
9. After!the!circuit!is!constructed,!place!
the!multimeter!probes!on!either!side!
of!each!resistor!and!record!the!
voltage!from!the!display!of!the!
multimeter.!
!
NOTE:!Make!sure!that!the!red!(+)!
probe!is!on!the!same!side!that!the!
schematic!shows!to!be!+!in!respect!to!
that!resistor.!Otherwise,!it!will!show!
the!same!magnitude,!but!with!
opposite!sign!–!i.e.!it!will!show!the!
voltage!as!negative.!
