find the applied voltage

### Circuit Diagram Analysis

**Components and Configuration:**

- The circuit features a series of resistors and a voltmeter.
- Resistors:
  - A 2 kΩ resistor is connected on the left side of the circuit.
  - An 18 kΩ resistor is connected on the right side.
  - A 20 kΩ resistor is connected at the bottom.
  - Another 20 kΩ resistor is connected parallel to the voltmeter in the middle section.

- **Voltmeter (V):** Positioned centrally, labeled with a measurement of 20 V.

**Connections:**

- The circuit is powered by an applied voltage source denoted as \(V_{\text{applied}}\).
- The resistors and voltmeter create a network around the circuit, forming a loop.

**Operational Details:**

- The voltmeter measures the voltage across the middle branch of the circuit.
- Current flows through the circuit, distributing voltage according to the resistance values.

This circuit diagram is a representation of a fundamental electrical network useful for understanding series and parallel resistor configurations and the function of a voltmeter in measuring potential differences across a section of the circuit.

Electrical Engineering homework question answer, step 1, image 1

As the Voltage across 20 KΩ resistor is given 20 V, and the voltage across another 20 KΩ resistor will be also 20 V as both resistor are connected in parallel. In case of Parallel Connection the voltage remains same.
