What result do you expect in above experiment, if by mistake, voltmeter is connected in series with the resistance.

Explanation

### Step-by-Step Solution

1. **Understanding the Setup**: In the experiment, we have a resistor (R) and a voltmeter. Normally, the voltmeter should be connected in parallel with the resistor to measure the voltage across it.

2. **Connecting the Voltmeter in Series**: If the voltmeter is mistakenly connected in series with the resistor, the circuit configuration changes. The voltmeter, which has a very high internal resistance (let's denote it as R_v), is now part of the same circuit path as the resistor.

3. **Analyzing the Circuit**:
- When connected in series, the total resistance in the circuit becomes the sum of the resistor and the voltmeter's internal resistance:
...
