Question

The ways A, B and C of measuring a resistance are shown. Assuming R is low. The correct way of measuring is

• A. C
• B. A
• C. B
• D. any of these is correct

Answer 1

Answer: (C)

B

to measure the resistance , the voltage across the resistor is measured by voltmeter in parallel and the current through the resistor is measured by the ammeter in series.

$R=\frac{V}{I}$

B is the correct way for measuring resistor.
