Finding E

Postby Guadalupe T 1E » Fri Mar 16, 2018 12:13 pm

Are there instances when you can only use cathode-anode or any when you can only flip the value? Or can we always use either?

You should be able to use either. As long as you identify the anode and cathode correctly

You can use either method of solving for E, but just make sure you stay consistent and don't combine the two. If you use cathode-anode, then don't flip the sign of the E for the anode.

If you flip the sign, use Ecell=Eanode+Ecathode. If you don't flip the sign, use Ecell= Ecathode-Eanode.
