The input resistance of a VTVM is about ______________?
Correct answer: D. 10 MO
- A. 1000 O
- B. 10 kO
- C. 20 kO
- D. 10 MO
Explanation
A VTVM uses a vacuum-tube or electronic amplifier input, giving it a very high input resistance, typically about 10 MΩ. This high resistance minimizes loading of the measured circuit.
