Which of the following is the SI unit for measuring electric current?
A
(watt)
B
(ohm)
C
(volt)
D
(ampere)
Verified step by step guidance1
Understand that electric current is the flow of electric charge through a conductor per unit time.
Recall that the SI unit for electric current is defined as the ampere (A), which measures the amount of charge passing a point per second.
Recognize that watt (W) is the SI unit of power, which measures the rate of energy transfer.
Know that ohm (Ω) is the SI unit of electrical resistance, which measures how much a material opposes the flow of current.
Identify that volt (V) is the SI unit of electric potential difference or voltage, which drives the current through a circuit.
