For example, if we have to create 1 ampere of current flow through a circuit by 100 volts, then the resistance is 100 ohms. The voltage required for creating 1 ampere of current to flow through the circuit is known as the resistance. Kiloohms KΩ, megaohms MΩ, milliohm, and so on are known as the higher multiple and sub-multiple values of Ohm. The SI unit of resistance is known as Ohm Ω. Here, the resistance R is constantly proportional.

What is Resistance?īased on Ohm's law named after German Physicist Georg Simon Ohm, the resistance is defined as follows:Īs per the Ohm's Law, the voltage V across a resistor is directly proportional to the current I flowing through it. The ease at which the electrons will allow the electricity to flow through it is known as resistance.Īn insulator has better resistance than the conductor, and the term resistance is defined as the electrical quantity used by the resistor to control the flow of electrons. The total voltage passes through when it is passed through a conductor like the metal by introducing the resistors, the amount of voltage and current can be controlled. However, the resistor determines the amount of electricity that is allowed to pass through them. Insulators do not allow the flow of electrons, but the conductor does. Here, two categories can be identified which are conductors and insulators. The basic idea is known to all about how electricity flows through an electronic circuit. It's made up of copper wires that are wrapped around a ceramic rod and coated with insulating paint. The most important and commonly used components in an electronic circuit are resistors.Ī resistor's main job is to reduce current flow and lower voltage in a specific section of the circuit. And it also allows us to introduce a controlled amount of resistance into an electrical circuit. Inverted siphons are commonly used for under-the-road water flow.The term 'resistor' refers to a device that acts as a two-terminal passive electrical component that is used to limit or regulate the flow of electric current in electrical circuits.

We can use this theorem to calculate pressure, velocity and the elevation for a siphon tube. V= Velocity of the fluid at the lower elevation The Bernoulli’s theorem applies to Siphon also which states that the pressure, potential energy, and kinetic energy remain constant of a fluid flow inside a tube. We need the atmospheric pressure difference for the initial start of the flow, and then we need the cohesive force and the gravitational potential difference to keep the flow continuing. So the summary is that we need to have all mentioned factors into consideration for a siphon to work property. Of course, in this case, also, you need to create the initial pressure difference manually or using an alternate method. The potential energy difference at different ends of the tube causes the flow of liquid. This principle is also called the chain model, as the heavier chain in the long tube always pulls the lighter chain in the short tube to keep the liquid flow continuing. The chain model, where the section marked “B” pulls down because it is heavier than the section “A”
