What is difference between current and voltage?In: College Degrees |
[Edit] |
Answer
Consider what voltage is and then what current is and, after consideration, compare the two to see the difference. Voltage, or electromotive force, can be thought of as "electrical pressure" that has the ability to force electrons to flow. And current is the actual movement of those electrons. Voltage, whatever its source, must be present to make electrons move. There can be voltage, that force that will make electrons move, present in a circuit without any current flow if there is no complete path in that circuit. At the wall outlets in one's home, one will find voltage without anything being plugged in. It's just waiting to go to work moving herds of those little critters we call electrons. When a circuit is actually completed, when we turn on something that's plugged into an outlet, the voltage actually heads those little electrons up and moves them out and presto! current flow!
