Problem 3
Find voltages V1and V4(in terms of Vsand the resistances) using each of the following methods:
(a) use voltage division and series/parallel combination of resistors.
(b) use mesh analysis to determine I1and I2, then V1=R1I1and V4=R4I2.
(c) use nodal analysis to find Va,Vband Vc, then V1=Va−Vband V4=Vc.
