Consider a circuit made of 2 resistors wired in parallel. If the same two resistors were wired in series, the total resistance of the circuit would ____________. *
a. increase
b. decrease
c. stay the same
d. You cannot compare the resistances, since no values are given.
in parallel, the resistance decreases, since the current can flow through two paths 1/R = 1/R1 + 1/R2
in series, the resistance increases R = R1 + R2
so, what do you think?
