What is the unit of electric current?
Explanation
Ampere is the SI unit of electric current. Option A (“Voltage”) is incorrect because it represents a different unit, dimension, instrument, quantity or measurement relationship from the one asked. Option B (“Current”) is incorrect because it represents a different unit, dimension, instrument, quantity or measurement relationship from the one asked. Option C (“Resistance”) is incorrect because it represents a different unit, dimension, instrument, quantity or measurement relationship from the one asked. Match the quantity with its definition, SI unit and dimension. Option A, “Voltage”, is incorrect for this question because it does not match the precise location, process, landform, climatic feature or geographical relationship identified by the evidence. Option B, “Current”, is incorrect for this question because it does not match the precise location, process, landform, climatic feature or geographical relationship identified by the evidence. Option C, “Resistance”, is incorrect for this question because it does not match the precise location, process, landform, climatic feature or geographical relationship identified by the evidence.
