of wire having a resistance R is cut
into
five equal parts .
a. how does
the resistance of each part
compare
with
the original resistance ?
b. when connect in parallel find
resistance
compare
with original resistance .
c. two connected in series and three connected
in
parallel compare with
original resistance .
d. three connected in
series and two
connected
in
parallel compare with
original resistance .
