What is Ohm's Law
200
What happened to the current in a series circuit when the resistance was increased?
What is it decreases?
300
Current is equal to the voltage difference of a circuit divided by its resistance.
What is Ohm's Law?
300
Law that says that charges can transfer from one object to another, but cannot be created or destroyed.
What is the Law of Conservation of Charge?
300
The part of a circuit that slows the electrical current.
