Assignment 1 Due 21 August 2020
1. Use the principle of superposition to determine the current io through R1 in Figure
below:[15]
Let R1 = 8Ω , R2 = 2Ω , R3 = 3Ω , R4 = 4Ω , R5 = 2Ω , V1 = 15V, I1 = 2A, I2 = 3A.
2. Using mesh analysis, find the currents I1, I2, and I3 in the circuit of Figure below:[15]
3. In the circuit shown in Figure below, the mesh currents are I1 = 5A, I2 = 3A and I3 =
7A .[18]
Determine the branch currents through:
a. R1.
b. R2.
c. R3.
4. Use nodal analysis in the circuit of the Figure below to find the voltages at nodes A, B,
and C.
Let V1 = 12V, V2 = 10V, R1 = 2Ω, R2 = 8Ω, R3 = 12 Ω, R4 = 8 Ω.[18]
5. [12]
6. In the diagram below, circuit nodes A through E each have one or more current
flows into and out of them. You have been given some of the current values, and
are required to apply Kirchhoff's current law to determine the value of the
unknown currents I1 through I5. [12]
Find the unknown currents entering and leaving the node
