The difference of electrical potential between two points of an electrical or electronic circuit, expressed in volts. It measures the potential energy of an electric field to cause an electric current in an electrical conductor.

Between two points in an electric field. A good example is that which exists in an electrical circuit, the difference in their electrical potentials is known as the electrical potential difference. This difference is proportional to the electrostatic force that tends to push electrons or other charge-carriers from one point to the other. Electrical potential difference can be thought of as the ability to move electrical charge through a resistance.

To understand "potential difference" you first have to understand "potential."

Every point wthin an electric circuit has a certain "potential." The potential is a measure of how much potential energy each electron has at that point. The potential energy is there because electrons naturally repel each other (you may have heard that "like charges repel"). So squeezing them all together into a small space--while they're trying to repel each other--is a little like trying to compress a spring and store it into a small box. The spring has potential energy (waiting to be released when someone opens the box); and the electrons have potential energy in a similar way.

Another way to think about potential is that it's similar to water pressure. This is a good analogy, since the electrons flow through a circuit somewhat as water flows through pipes.

"Potential difference" just refers to the difference in potential between two points in a circuit. You can pick any two points and determine what the potential difference is between them. It's similar to measuring the difference in water pressure between two points in a plumbing system. You just subtract one potiential from the other to get the potential difference.

Potential, and potential difference, are measured in Volts.

The reason potential difference is important is that it helps determine whether electrical current will flow between the two points and, if so, how fast it will flow. Again, this is like water pressure. If two points in your plumbing are both at the same pressure, than no water can flow between them. But if there's a huge difference in pressure, then the water will flow pretty fast (assuming there's a pathway between the two points). In the same way, if two points in a circuit are at the same potential (say, 5 volts), then no current can flow between them. But if one point is at 5 V and another point is a 30 V, then current can flow.

Try to be more confident and find YOU ARE HOW YOU FEEL ABOUT YOURSELF! Loving and accepting ourselves is THE MOST CRITICAL FACTOR in experiencing joy,happiness, and success in life. When you really love yourself and you really love other people, you find that life is really an incredible journey where things flow, and no matter what happens you always find a way to enjoy yourself and you feel fulfilled. You MUST love yourself completely. This determines your STANDARDS for what you are willing to accept or settle for. It determines how well you treat your body and your health, how much money you feel you deserve to earn or feel you can make, your belief in whether you can achieve your goals, how much others RESPECT you and how they treat you, and even whether people like you and want to be around you. People love being around confident people. You see, confident people do not feel the need to judge you or tear you down in order to elevate their own self-worth. They radiate a positive energy. You feel safe around them. You need to consistently and confidently take action to move towards your goals, and towards your ultimate destiny. People who lack in confidence often get ‘stuck’. So you see, your entire DESTINY is shaped by your degree of confidence. True self-confidence comes from an absolute sense of certainty deep within, that you are able to handle anything life throws your way. Truly confident people exude calm, control, power, certainty. They care about people, and they make people feel good when they are around them.They never brag – after all, actions speak louder than words. People who brag are just masking their insecurities. People have varying degrees of confidence depending on what activity they are performing. For example, someone might be totally confident in performing a piano concert, or driving a car, but feel totally inadequate at a new job they’ve started, or at flirting with members of the opposite sex. People with Total Self-Confidence, though, have complete belief in themselves. They never ask themselves “Can I really do this? What if this doesn’t work out? Am I good enough to pull it off?” They know that if they really want something, and they are committed to getting it, it will happen. They know that it’s just a question of time until they’ve mastered the skills and knowledge to make whatever they want a reality.
