How can the tension in a conductor be measured?

• A. With a multimeter
• B. With a dynamometer
• C. By visual inspection
• D. With an accelerometer

Answer: (B)

The tension in a conductor can be accurately measured using a dynamometer. A dynamometer is a device designed to measure force, torque, or power, and is specifically suitable for assessing the tension in cables or conductors. It provides a direct and quantitative measurement, which is crucial for ensuring that the tension remains within safe limits to prevent damage to the structure or the conductor itself.

A multimeter, while useful for measuring electrical parameters such as voltage, current, and resistance, cannot measure mechanical tension directly. Visual inspection may help identify issues like sagging or wear, but it does not provide precise numerical values for tension. An accelerometer measures acceleration and would not be applicable for determining the tension in a conductor. Thus, the use of a dynamometer is the most effective and accurate method for this specific measurement.
