10.2: Electromotive Force
The voltage output of the battery charger must be greater than the emf of the battery to reverse the current through it. This causes the terminal voltage of the battery to be greater than the emf, since (V = epsilon - Ir) and I is now negative.

Problem. Current is the amount of charge that is flowing through a component per unit of time. For a given voltage, Ohm''s law tells us that if we increase the resistance, then the current must decrease.

Ohm''s Law. The higher the voltage v the higher the current. If the brightness is caused by a flow of electrons through the filament, a higher voltage will--all things being equal-- drive more electrons to flow through the filament. So the brightness is a function of both current and voltage, and can be said to depend on both.

What is more dangerous and how? Voltage or current?
Voltage with no current is just a battery, or an open circuit. A wall outlet with nothing plugged in. A current with no voltage I''m pretty sure can''t exist. To say one is safer than the other doesn''t really make logical sense. Electricity can exist in all forms, high voltage low current, high current low voltage, both high, and both low.
