# MCQs on Voltage Questions and Answers ## Voltage – Definition

Voltage is an electrical pressure or potential difference which help to flow the current. Voltmeter is used to measure the voltage in any circuit. The SI unit of voltage is volt. Voltage can be alternating (AC) or direct (DC). The symbol of voltage is V or E. The term voltage introduced by Italian Physicist Alessandro Volta (1745-1827). All the MCQs on Voltage Questions and Answers are published according to the new study syllabus for academic year 2021-22.
