Consider the horizontally-oriented 1kΩ resistor that is forming the "bridge" in the bridge circuit below. Which of the following statements about the current in this resistor is correct? It flows from right to left No current is flowing through this resistor It flows from left to right The current through this resistor is negative
KVL and KCL
KVL stands for Kirchhoff voltage law. KVL states that the total voltage drops around the loop in any closed electric circuit is equal to the sum of total voltage drop in the same closed loop.
Sign Convention
Science and technology incorporate some ideas and techniques of their own to understand a system skilfully and easily. These techniques are called conventions. For example: Sign conventions of mirrors are used to understand the phenomenon of reflection and refraction in an easier way.

![This image illustrates an electrical circuit with resistors in a combination of series and parallel configurations.
**Description of the Circuit:**
1. **Power Source:**
- There is a symbol representing a DC power source (battery) on the left.
2. **Resistor Configuration:**
- The circuit has four resistors labeled with their resistance values in ohms (Ω).
- From the top:
- **First Resistor:** 1kΩ (1000 ohms) in series.
- **Second Resistor:** 500Ω (500 ohms) in series with the first.
- Parallel Resistor Arrangement:
- Between the junctions of the first two resistors is a parallel pair of resistors:
- **Third Resistor:** 1kΩ (1000 ohms).
- **Fourth Resistor:** 500Ω (500 ohms).
3. **Connections:**
- The series arrangement proceeds vertically downwards with the two resistors (1kΩ and 500Ω).
- From the junction between these two resistors, a parallel 1kΩ resistor is connected to a parallel 500Ω resistor, creating a bridge between the series-connected paths.
- The bottom of the parallel resistors reconnects to the series path leading back to the power source.
This circuit demonstrates how resistors can be arranged to create different total resistance through a combination of series and parallel connections. The total resistance affects how current flows in the circuit, which can be calculated using the rules for combining resistors in series and parallel.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe09d4462-f34d-4530-ac40-5ce52271c7b7%2F4c4fe736-e760-4a4c-aeab-be0a636aba01%2Fk47egu_processed.png&w=3840&q=75)
