Step 1

To do this, we assign a node voltage to each node in the circuit. Let's call the node voltages as follows: Node A: VA Node B: VB Node C: VC Now, we can write the nodal equations for each node: At Node A: (VA - VB)/Rs + (VA - VC)/R4 = 0 At Node B: (VB - VA)/Rs Show more…

sir Q3-a. Write the nodal equations for the network of Fig. 3 using the general approach. b. Solve for the nodal voltages. c. Find the voltage across the resistor R4 in Figure 3. Rs = 20Î© R4 = 4Î© R = 90Î© R = 180Î© V = 16V Figure 3 Q4. For the bridge in Fig. 4: a. Write the mesh equations using the format approach. b. Determine the current through R5. c. Is the bridge balanced? R = 33Î© R = R Rs = R > 2kÎ© MM = 20mA R = 3.3kÎ© R = 5.6Î© Figure 4
