(A) : The resistance of voltmeter is very small as compared to the resistance of the galvanometer, from which it is obtained.
(R) : The voltmeter is connected in series to the conductor across which potential difference is to be measured.

Options

A. Both 'A' and 'R' are true and 'R' is the correct explanation of 'A'.
B. Both 'A' and 'R' are true and 'R' is not the correct explanation of 'A'
C. 'A' is true and 'R' is false
D. 'A' is false and 'R' is false

Answer

To solve the question, we need to analyze the statements (A) and (R) regarding the voltmeter and the galvanometer.

### Step-by-Step Solution:

1. **Understanding Statement (A)**:
- The statement claims that "The resistance of a voltmeter is very small as compared to the resistance of the galvanometer, from which it is obtained."
- This statement is incorrect. A voltmeter is designed to have a **high resistance** to ensure that it does not draw significant current from the circuit it is measuring. This allows it to measure the potential difference without affecting the circuit.

2. **Understanding Statement (R)**:
- The statement claims that "The voltmeter is connected in series to the conductor across which potential difference is to be measured."
- This statement is also incorrect. A voltmeter should be connected in **parallel** to the circuit element across which the voltage is to be measured. If it is connected in series, it would alter the current flowing through the circuit, leading to an inaccurate measurement.

3. **Conclusion**:
- Since both statements (A) and (R) are incorrect, we conclude that both the assertion and the reason are false.

### Final Answer:
Both statements (A) and (R) are false.
