Voltage definition for dummies. The voltage is equivalent to the water pressure the current is equivalent to the flow rate and the resistance is like the pipe size. It says that the current is equal to the voltage divided by the resistance or i v r. Voltage is the water pressure and ampere current is the flow of the water. Ohms law for dummies.
A car battery provides about 12 v. Often you know the voltage and the wattage of the circuit and you want to use those values to determine the amount of current flowing through the circuit. Voltage is the difference in charge between two points. Dont be so hard on yourself you re not dumb.
There is a basic equation in electrical engineering that states how the three terms relate. Now if you have a pipe which that water needs to flow through and the water pressure on one side is more than the pressure is on the other side it will cause the water to flow. Ill cut out all the excess and. It is made up of conductors which rotate through a magnetic field to provide voltage or force by electromagnetic induction.
The voltage is a kind of electrical force that makes electricity move through a wire and we measure it in volts. The voltage that s available in a standard electrical outlet in the united states is about 117 v. Resistance is a material s tendency to resist the flow of charge current. Voltage is usually supplied by a battery or a generator.
This is known as ohm s law. The definition of one watt is simple. For dummies lets compare it to water. Armature the movable part of a generator or motor.
So a 12 volt car battery will generally produce more current than a 1 5 volt flashlight battery. Electrical current is measured in amperes or amps. So when we talk about these values we re really describing the movement of charge and thus the behavior of electrons. Basic electrical terms and definitions.
Electricity is an extremely difficult concept to understand which is why today you re going to learn from me a dummy how i learned the fundamentals of electricity. The voltage available in a flashlight battery is about 1 5 v. Apparent power is the product of the rms voltage and the rms current. The scientific symbol for voltage is the letter e dating back to the early days of electricity when it was called electromotive force electricians and wiring books use the letter v for volts current is electricity in motion.
