A "volt" is a unit of electric potential, also known as electromotive force, and represents "the potential difference between two points of a conducting wire carrying a constant current of 1 ampere, when the power dissipated between these points is equal to 1 watt.

The characteristics of voltage are like that of water flowing through pipes. This is known as the "water-flow analogy", which is sometimes used to explain electric circuits by comparing them with a closed system of water-filled pipes, or "water circuit", that is pressurized by a pump. Refer to the image below to visualize how voltage and electric current works Current I is a rate of flow and is measured in amps A. Ohms R is a measure of resistance and is analogous to the water pipe size.

Current is proportional to the diameter of the pipe or the amount of water flowing at that pressure. Voltage is an expression of the available energy per unit charge which drives the electric current around a closed circuit in a direct current DC electrical circuit. Switching to a higher-voltage system would provide more power with thinner-gauge wiring.

The switch never happened , because carmakers were able to boost efficiencies with digital technology and more efficient electric pumps at 12 volts.

But some new models employ hybrid systems with a separate volt generator to power advanced features like idle shut-off while increasing overall system efficiency. Sign up for our Newsletter!

Electrical Efficiency " ". Electrons can't resist this trip, just like when you drop a ball on a slope. The law of gravity forcing the ball electrons to roll is the voltage or electrical voltage. When the ball is at any point on that slope, all the descent that lies ahead is its potential energy. The volts symbol V measure the different potential energy that exists between one point and the other.

The volts are thus named in honor of Alessandro Volta, the inventor of the battery. You should care because your life is full of voltages. If you look at any plug you will see two holes. Imagine that one of them is the highest point of the slope and the other is the end.

Between the two points there is a difference of volts. Amperes measure the intensity of an electric current. Continuing with the analogy of the ball and the slope, the amps serve to tell us the amount of energy how many balls?

The amp-hour Ah symbol expresses how much power can be circulated by a given circuit for one hour. It is used to measure the capacity of the electric batteries. Create a personalised content profile.
