## Bridge Circuit Analysis
Consider the following figure of a bridge circuit:
### Diagram Description:
The diagram illustrates a bridge circuit composed of certain resistors connected in a specific configuration. Here is the detailed breakdown of the arrangement:
- **Resistors:**
- **1 ohm** between points C and A.
- **2 ohms** between points C and D.
- **1 ohm** between points C and E.
- **2 ohms** between points B and E.
- **1 ohm** between points D and E.
- **Points:**
- **A, B, C, D, and E** are different points in the circuit.
- **Voltage Source:**
- A 14V voltage source is connected between points A and B.
- **Currents:**
- **I**: Total current provided by the voltage source.
- **I1, I2, I3, I4, I5**: Currents flowing through different branches of the circuit (as shown by the arrows).
### Questions and Calculations:
#### (a) Find the currents \( I, I_1, \ldots, I_5 \) in the bridge circuit in the figure.
**Solution Fields:**
- \( I = \) __ amps
- \( I_1 = \) __ amps
- \( I_2 = \) __ amps
- \( I_3 = \) __ amps
- \( I_4 = \) __ amps
- \( I_5 = \) __ amps

#### (c) Can you change the resistance in branch BC (but leave everything else unchanged) so that the current through branch CE becomes 0?
**Options:**
- [ ] Yes
- [ ] No
### Detailed Explanation:
**Bridge Circuit**: A bridge circuit is used to measure unknown resistances and consists of four resistances in a diamond shape with a voltage source connected across one diagonal and the measurement taken from the other diagonal.
To solve for currents and the effective resistance, you'll apply Kirchhoff's laws:
- **Kirchhoff's Voltage Law (KVL):** The sum of all voltages around any closed loop in a circuit must equal zero.
- **Kirchhoff](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F715e5f42-2b41-4404-933d-923c40f8873c%2F98f2ca06-3843-4987-9f68-a46f4b707f42%2Feoqqadl_processed.jpeg&w=3840&q=75)
