Understand Ohms Law
Ohms’ Law describes the relationship between Voltage, Current and Resistance. Named after Georg Ohm who discovered this relationship in 1827. He discovered some laws relating to the strength of a current in a wire. Ohm found that electricity acts like water in a pipe. Ohm discovered that the current in a circuit is directly proportional to the electric pressure and inversely to the resistance of the conductors.
Ohm’s law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Wikipedia

An electric circuit is formed when a conductive path is created to allow the electric charge to continuously move. This continuous movement of electric charge through the conductors of a circuit is called a current, and it is often referred to in terms of “flow,” just like the flow of a liquid through a hollow pipe

The force motivating charge carriers to “flow” in a circuit is called voltage. Voltage is a specific measure of potential energy that is always relative between two points. When we speak of a certain amount of voltage being present in a circuit, we are referring to the measurement of how much potential energy exists to move charge carriers from one particular point in that circuit to another particular point. Without reference to two particular points, the term “voltage” has no meaning.

Current tends to move through the conductors with some degree of friction, or opposition to the motion. This opposition to the motion is more properly called resistance. The amount of current in a circuit depends on the amount of voltage and the amount of resistance in the circuit to oppose current flow. Just like the voltage, resistance is a quantity relative between two points. For this reason, the quantities of voltage and resistance are often stated as being “between” or “across” two points in a circuit.
