Q. Volt is the ornamental name for

A
Watt per hour
B
Watt-hour
C
Joule second
D
Joule per coulomb
Solution:

The volt (symbol: V) is the derived unit for electric potential, electric potential difference (voltage), and electromotive force.[1] It is named after the Italian physicist Alessandro Volta.

Voltage is electric potential energy per unit charge, measured in joules per coulomb ( = volts). It is often referred to as “electric potential”, which then must be distinguished from electric potential energy by noting that the “potential” is a “per-unit-charge” quantity.
