Math Problem Statement
Solution
The problem involves using nodal analysis to find the voltages and in the circuit.
Circuit Information:
- The circuit has two nodes labeled and .
- There are resistors with values , , and .
- A current source is connected between node and ground.
- A voltage source with across it is connected in the circuit.
Steps for Nodal Analysis:
-
Identify Nodes:
- is the voltage at the node where the 2A current source is connected.
- is the voltage at the node with the voltage source connected.
-
Set Up Equations:
- Apply Kirchhoff's Current Law (KCL) at nodes and .
-
KCL at Node :
- Assume currents leaving the node.
-
