Hi guys. I just want to check my information about voltage if it's right. I know that electrons in copper wires move randomly but when we apply a voltage like a battery has two terminals one negative and one positive the electrons are attracted to the positive terminal and move in a speed of millimetres per hour but electric current move at the speed of light and electrons gain kinetic energy like if we have a 6 volt battery it means on columb will gain 6 joules of energy or we have to do work equals 6 joules to move charge from a tetminal to which it is attracted,, and when we apply a higher voltage electrons move in a higher speed and thus increasing the current, is that right ? Please say yes or no???!
