Question

In each circuit find the voltage or current indicated

### Electrical Circuit Analysis #### Image Description: The image contains four distinct electrical circuit diagrams, each representing different configurations of resistors, voltage sources, and current sources. #### Diagram 1: 1. **Voltage Source:** - 72V source. 2. **Resistors:** - Resistor of 12 kΩ in series with a parallel combination of two resistors: 6 kΩ and one with an unknown resistance (denoted by the current i). 3. **Current Source:** - 4 mA current source in parallel with the 6 kΩ resistor. 4. **Note:** - The current i is flowing down through the resistor in parallel with the 6 kΩ resistor. #### Diagram 2: 1. **Current Sources:** - Two current sources: 8 mA and an unknown (labeled i). 2. **Resistors:** - Resistor of 3 kΩ in parallel with two other resistors: 1 kΩ and 4 kΩ. 3. **Voltage Source:** - 24V source across the 4 kΩ resistor. 4. **Note:** - The current i is flowing down through the 4 kΩ resistor. #### Diagram 3: 1. **Voltage Source:** - 20V source. 2. **Resistors:** - 2 kΩ resistor in parallel with another unknown value resistor. 3. **Current Source:** - 5 mA current source in parallel with the 2 kΩ resistor. 4. **Note:** - The current i is flowing up through the 20V source. #### Diagram 4: 1. **Voltage Sources:** - Two voltage sources: 90V and 30V. 2. **Resistors:** - Two resistors: 3 kΩ and 1.5 kΩ in series with a resistor of 2 kΩ, creating multiple loops. 3. **Voltage Notation:** - The voltage across the 3 kΩ resistor is denoted by v. 4. **Note:** - The circuit forms a complex loop system for detailed analysis. ### Explanation: Each diagram depicts a different scenario and setup for the analysis of electrical properties such as current, voltage, and resistance. These configurations are fundamental exercises in electrical engineering courses to help understand concepts like Ohm’s Law, Kirchhoff
