$3.$ Run$3$ experiments changing only the current.

$-$ From the menu, chose any metal for an anode, corresponding metal for a cathode, and a solution$$

$-$ set up a current to $3\mathrm{.}00$ Amps, set up a timer for $20$ minutes, record the mass loss and gain

$-$ set up a current to $6\mathrm{.}00$ Amps, set up a timer for $20$ minutes, record the mass loss and gain

$-$ set up a current to $12\mathrm{.}00$ Amps, set up a timer for $20$ minutes, record the mass loss and gain
