What Is The Work Of Resistance

We measure current in amperes.

What is the work of resistance. Devices called resistors let us introduce precisely controlled amounts of resistance into electrical circuits. The basic unit of electrical resistance is the ohm as already mentioned. Ohm defines the unit of resistance of 1 ohm as the resistance between two points in a conductor where the application of 1 volt will push 1 ampere or 6 241 10 18 electrons. Resistance training is any exercise that causes the muscles to contract against an external resistance with the expectation of increases in strength tone mass and or endurance.

The electrical resistance of a circuit component or device is defined as the ratio of the voltage applied to the electric current which flows through it. Resistance is one of three basic quantities in electrical or electronic circuits. Current is the flow of electrons through a circuit. If the resistance is constant over a considerable range of voltage then ohm s law i v r can be used to predict the behavior of the material.

The circuit with the higher resistance will allow less charge to flow meaning the circuit with higher resistance has less current flowing through it. Resistance to change is the act of opposing or struggling with modifications or transformations that alter the status quo. Ohms are named after georg simon ohm 1784 1854 a german physicist who studied the relationship between voltage current and resistance. Four typical resistors sitting side by side in an electronic circuit.

In my next book uncovering happiness can t wait to share it with you january 2015 i explore some of the neuroscience behind what keeps us stuck in a depressive loop and how to get unstuck and even find our natural anti. Whether you want to sit and meditate work on a new project get out and exercise whatever it is that is in the direction of growth resistance comes alive. A conductor has low resistance while an insulator has much higher resistance. This brings us back to georg ohm.

This is often denoted by the greek symbol ω. This resistance can manifest itself in one employee or in the workplace as a whole. A resistance decade box or resistor substitution box is a unit containing resistors of many values with one or more mechanical switches which allow any one of various discrete resistances offered by the box to be dialed in. Let s take a closer look at what they are and how they work.

Resistance is a measure of the opposition to current flow in an electrical circuit. The external resistance can be dumbbells rubber exercise tubing your own body weight bricks bottles of water or any other object that causes the muscles to contract. Resistance is measured in ohms symbolized by the greek letter omega ω.
