What is the current of I1, I2 and I3
Transcribed Image Text:**Electrical Circuit Diagram and Component Values**
This diagram illustrates an electrical circuit consisting of resistors, voltage sources, and current paths. Below is a detailed description of the circuit and the components involved.
**Circuit Components:**
1. **Resistors:**
- \( R_1 \) is in series with voltage source \( V_1 \).
- \( R_2 \) is in series with voltage source \( V_2 \).
- \( R_3 \) is connected between the paths of currents \( I_1 \) and \( I_2 \).
2. **Voltage Sources:**
- \( V_1 \) is connected across \( R_1 \) and provides a potential difference of 20V.
- \( V_2 \) is connected across \( R_2 \) and provides a potential difference of 40V.
3. **Currents:**
- \( I_1 \) flows through \( R_1 \).
- \( I_2 \) flows through \( R_2 \).
- \( I_3 \) flows through \( R_3 \) upwards between \( R_1 \) and \( R_2 \).
**Component Values:**
- \( R_1 \) = 10Ω
- \( R_2 \) = 20Ω
- \( R_3 \) = 30Ω
- \( V_1 \) = 20V
- \( V_2 \) = 40V
**Diagram Description:**
In the schematic diagram, the arrows indicate the direction of current flow:
- \( I_1 \) flows from the positive terminal of \( V_1 \), through \( R_1 \).
- \( I_2 \) flows from the positive terminal of \( V_2 \), through \( R_2 \).
- \( I_3 \) flows upwards from the junction of \( V_1 \) and \( R_3 \) to the junction of \( V_2 \), passing through \( R_3 \).
This circuit setup can be used to understand the relationships between voltage, current, and resistance in series and parallel components, and to apply Ohm’s law and Kirchhoff's circuit laws to analyze the circuit.
