Consider the circuit shown:
a. Use KCL to determine the unknown currents. Assume that
v_(s)
is 12 V , and that all Resistors are
10\Omega
.
i. Suppose that
R_(3)
becomes
5\Omega
, what happens to the currents?
ii. If
R_(1)
is opened, draw the resulting circuit, and determine all currents and voltages.
b. Use KVL to solve all parts of problem 2a. You should get the same answers.
