Question

before connecting the voltmeter between point A and ground, what is the voltage across R2?

The image shows an electrical circuit diagram featuring two resistors in series and a voltmeter. Here's a detailed explanation: **Circuit Components:** 1. **Voltage Source:** - A DC voltage source of 10 V is connected to the circuit. 2. **Resistors:** - \( R_1 \) and \( R_2 \) are resistors, each with a resistance value of 100 kΩ. - They are connected in series between the positive terminal of the voltage source and the ground. 3. **Voltmeter:** - A voltmeter is connected in parallel with \( R_2 \). - It measures the voltage across \( R_2 \). **Connection Points:** - Point \( A \) is the junction between \( R_1 \) and \( R_2 \). **Explanation:** - The circuit forms a simple series circuit with the voltage source providing 10 V. - The total resistance in the circuit is the sum of \( R_1 \) and \( R_2 \), which is 200 kΩ. - The voltmeter is used to measure the potential difference across \( R_2 \). This setup demonstrates basic concepts of series circuits and how voltmeters are used to measure voltage across components.
