Question 1

In nodal analysis, when a voltage source is connected between two non-reference nodes, which technique is used to write the nodal equations?

Question 2

Consider a circuit where node Va is connected to ground through R1=2\,kΩ, node Vb is connected to ground through R2=4\,kΩ, and a 10\,V source is connected with its positive terminal at Va and negative at Vb. Using nodal analysis with a supernode, what is Va?

Question 3

In an RL circuit with R=100\,Ω and L=0.5\,H, the initial current is 2\,A and the source is removed at t=0. What is the current at t=τ?

Question 4

In a series RC circuit with R=1\,kΩ and C=1\,μF, the capacitor is initially charged to 5\,V and then allowed to discharge. What is the capacitor voltage at t=2τ?

Question 5
