Voltage May Be Thought As Electrical
A substation is a part of an electrical generation transmission and distribution system.
Voltage may be thought as electrical. Voltage electric potential difference electric pressure or electric tension is the difference in electric potential between two points which in a static electric field is defined as the work needed per unit of charge to move a test charge between the two points. Normal aa size battery that you can find in your house has a potential difference of 1 volt between its positive and negative terminals. A transformer basically is very simple static or stationary electro magnetic passive electrical device that works on the principle of faraday s law of induction by converting electrical energy from one value to another. Between the generating station and consumer electric power may flow through several substations at different voltage levels.
The standard voltage of a home electrical outlet in the united states is 120 volts although the actual voltage supplied may be as low as 110 volts due to line conditions. The latter can be thought of as impedance. Sources of electric voltage. When the circuit is driven with direct current dc there is no distinction between impedance and resistance.
Electrical impedance extends the concept of resistance to ac circuits describing not only the relative amplitudes of the voltage and current but also the relative phases. Voltage is represented in equations and schematics by the letter v. In this analogy charge is represented by the water amount voltage is represented by the water pressure and current is represented by the water flow. Substations transform voltage from high to low or the reverse or perform any of several other important functions.
He is the inventor of the electric battery. It is the push that causes charges to move in a wire or other electrical conductor it can be thought of as the force that pushes the charges but it is not a force voltage can cause charges to move and since moving charges is a current voltage can cause a current. Similarly the voltage measured between the line and neutral points of a wall socket can be 230v or 110v. So for this analogy remember.
A few appliances like stoves and electric dryers may use 240 volts which require special wiring and outlets. When describing voltage current and resistance a common analogy is a water tank.
