# Electric Fields and Currents

1. The problem statement, all variables and given/known data

More of a general question:
I have a situation where I have a conductor at eight volts and a conductor with zero volts. Just because there is an electric field, does that mean there is an electric current present in the system? And what is the direction?

2. Relevant equations

None

3. The attempt at a solution

We just got introduced to this and I can't seem to find a reasoning. In my mind, I believe that there most likely must be a current, but I'm so green at this that I'm not sure.

Well, if you connect them there would be a current. If the condctors were connected to a voltage source, such as a battery, the current would continue to flow. If you connect them with a resistance Ohms law will tell you how big the current is.
If the conductors would be just 2 pieces of wire lying on a table there would only be current for a very short time if you connected them until their potentials became the same.

Since nothing connects the charges there will be no current
