Question

three-dimensional thinking
isabella uses a voltmeter to measure the voltage of a battery. the voltage reads 9 v when she measures both sides. make an argument about what the reading will be if she measures the same side of a battery. use evidence to support your argument.

Explanation:

A voltmeter measures the potential difference between two points. When measuring both sides of a battery, the voltmeter detects the full potential difference (9 V) between the positive and negative terminals. If Isabella measures the same side (e.g., two points on the positive terminal or two points on the negative terminal), there is no potential difference between those points—they are at the same electrical potential. Thus, the voltmeter reading will be 0 V.

Answer:

The reading will be 0 V.
