An industrial electrolytic cell requires a continuous current of 3.5 kA3.5\text{ kA}3.5 kA to deposit copper from a copper sulfate solution.
Which of the following is a correct equivalent unit for the ampere (A\text{A}A), derived from the fundamental definitions of potential difference and electric current?
joule-volt per second (J V s−1)\text{joule-volt per second } (\text{J V s}^{-1})joule-volt per second (J V s−1)
joule per volt-second (J V−1s−1)\text{joule per volt-second } (\text{J V}^{-1}\text{s}^{-1})joule per volt-second (J V−1s−1)
volt-second per joule (V s J−1)\text{volt-second per joule } (\text{V s J}^{-1})volt-second per joule (V s J−1)
joule per volt (J V−1)\text{joule per volt } (\text{J V}^{-1})joule per volt (J V−1)
