What is silver used as in electrical work?
Silver is used as a low resistance conductive material. Contactors and relays contact points are made of copper and are silver plated to obtain the lowest resistance between the moving contact faces. ...

What is current voltage power and resistance?
current - movement of electrical charges voltage - electrical force/pressure power - work done resistance - opposition to current inductive reactance - opposition to changes in current capacitive reactance - opposition to changes in voltage total impedance - vector sum of resistance, inductive reactance, and capacitive reactance etc. ...
What is resistance when lifting weight?
Resistance is the amount of contrary force against which your muscles must work in order to complete a movement. Most often, these are the weights being lifted or resistance bands being stretched. ...

Why car battery terminal heats up?
It's called resistance. Every electrical circuit has resistance to the "flow" of energy. This is how electric heaters work. Take a small diameter piece of wire, and put a lot of electrical current through it. The thinner the wire, the more it will heat up. If the wire is too thin, it will burn and break. This is why you want an adequate "gauge" of wire for your electrical needs. ...
If the current in a work piece is doubled what will be the effect on the heat energy produced?
P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4. P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4. P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4. P = I2R...

Why does a heating element get hot when current flows?
The current is doing work against the resistance of the material which makes up the heating element. Because it has resistance. -- Whenever electric current flows through a resistance, it loses energy equal to (current-squared) x (resistance). -- When we connect components in an electrical circuit, we use wire with the least possible resistance, so as not to lose energy in the wiring. -- When we want to warm up the lab, we use wire with significant resistance, in order to have it dissipate significant energy and...

What type of drama represented the impressionism period?
One work that is often associated with this period is Maurice Maeterlinck's work Pelléas et Mélisande, which was later the basis of an opera by Claude Debussy. ...
Asked in Ford
When the front gas tank is unhook out of a ford 150 how could the gas meter still be reading full?
Gas gauges work based on electrical resistance. When the float in the tank is moved up or down by the fuel level, it changes the resistance and the gauge reads differently. Some gauges read full if resistance is high and full is resistance is low. If I understood the question, you unhooked the gauge and it is reading full, that is because you have opened the electrical contacts to unlimited resistance. But, if the gauge was always reading full, before you disconnected...
What is the meaning of resistance force?
Resistance force is the force which an effort force must overcome in order to do work on an object via a simple machine. Resistance force, like most other forces, is measured in newtons or in pound-force. Resistance force is used to calculate the work output using the equation: Work output = Resistance force * resistance distance ...

How does the resistors work in a integrated circuit?
A resistor implements electrical resistance as a circuit element. It works in an integrated circuit by reducing current flow, and to lower voltage levels within circuits. ...

What three things are needed to have an operating electrical circuit?
Three things that are needed to have an operating electrical circuit are: 1. Electric potential difference or voltage. 2. Conductive path, which allows the movement of charges such as wire. 3. Resistor, which acts as an electrical resistance and loosely defines any object that uses electricity to do work. ...
