Concept:A voltmeter is made by adding a large series resistance to a galvanometer to limit current and measure voltage.
Explanation:A galvanometer is a sensitive current-measuring device.
To measure larger voltage, most of the voltage must drop across an added resistance.
This resistance must be high so the galvanometer receives only a small safe current.
It must be connected in series so the same current flows through the galvanometer and the resistance.
Therefore, a high resistance is connected in series with the galvanometer.
Answer:A. high resistance is connected to it in series
