What is the SI unit of current?

The correct answer is Ampere

Explanation:

• Electric current is a flow of electric charge.
• The SI unit of electric current is the ampere, which is often shortened to "amp". It is named after André-Marie Ampère, one of the main discoverers of electromagnetism.
• One ampere of current is defined as one coulomb of charge passing through a given point in a circuit in one second.

\({\rm{Electric\;curernt\;}}\left( {\rm{I}} \right) = \frac{{{\rm{Electric\;charge}}\;\left( {\rm{Q}} \right)}}{{{\rm{Time\;}}\left( {\rm{t}} \right)}}\)

Other Options:

• Coulomb: The coulomb is the SI unit of electric charge, not current. One coulomb is equal to the charge of approximately 6.242 x 10¹⁸ electrons.
• Ohm: The ohm is the SI unit of electrical resistance. It measures how much a material resists the flow of electric current.
• Volt: The volt is the SI unit of electric potential difference or electromotive force. It measures the potential energy difference per unit charge between two points in a circuit.
