Transcribed Image Text:### Question 3: Find the current (\(i_1\)) for the following circuit.
#### Circuit Diagrams:
**Diagram (a)**
- **Voltage Source:** 10V
- **Resistor:** 2Ω
- **Current Direction:** Left to right through the resistor.
- **Task:** Calculate the current \(i_1\).
**Diagram (b)**
- **Voltage Source:** 10V
- **Resistor:** 2Ω
- **Current Direction:** Right to left through the resistor.
- **Task:** Calculate the current \(i_1\).
**Diagram (c)**
- **Voltage Source:** 10V
- **Resistor:** 100mΩ (0.1Ω)
- **Current Direction:** Left to right through the resistor.
- **Task:** Calculate the current \(i_1\).
**Diagram (d)**
- **Voltage Source:** 1kV (1000V)
- **Resistor:** 2Ω
- **Current Direction:** Right to left through the resistor.
- **Task:** Calculate the current \(i_1\).
### Instructions:
For each circuit:
1. **Apply Ohm's Law:** \(I = \frac{V}{R}\)
- Where \(I\) is the current, \(V\) is the voltage, and \(R\) is the resistance.
2. **Calculate the Current \(i_1\):** Substitute the given values for voltage and resistance into the formula to find the current flowing through each circuit.
3. **Direction Consideration:** Pay attention to the specified direction of the current flow in each diagram.
