What is a Voltmeter?

Your car’s battery carries a charge measured in volts. The battery produces this charge through the chemical reaction produced when a positively charged lead pole and a negatively charged lead pole are immersed in a sulfuric acid solution. The charge builds to a given potential regulated by the amount of oppositely charged poles used. The charge in a battery is measured using a voltmeter.

A voltmeter is a device that measures the electrical potential difference between tow oppositely charged units. In the case of your car’s battery, these units are the positive and negative poles on either side of the battery. The most accurate voltmeters are digital and provide an accurate account of the voltage within 1%. Analog voltmeters use a needle to point to the charge level. Analog voltmeters must be calibrated before use.

At Ed Koehn Ford Lincoln of Greenville, we use the latest equipment to measure the voltage in your car battery. Come visit our service facility soon!
