Question 1

A student records four different experimental measurements, each having the same numerical value of 2.5 but with different SI prefixes:

  • A time interval of 2.5 ns2.5\text{ ns}2.5 ns
  • A capacitance of 2.5 μF2.5\text{ }\mu\text{F}2.5 μF
  • A current of 2.5 mA
  • A potential difference of 2.5 kV2.5\text{ kV}2.5 kV

Which of the following lists these measurements in order of increasing magnitude?

potential difference, current, capacitance, time interval

time interval, capacitance, current, potential difference

time interval, current, capacitance, potential difference

capacitance, time interval, current, potential difference
