Summary: Describe Methods Of Producing C. And D. C Electricity
Assignment 2 unit 3
Describe methods of producing A.C. and D.C electricity.
There are two type of electric current it is known as direct current (DC). The other one is known as alternating current (AC). However, an electric current can be produce by moving a magnet inside a coil, wire, so the size of this induces current and it is able to increase by moving the magnet faster. This is using a stronger magnet, so increasing the number of the turns, coils. It may be able to increase its area but the dynamo is a type of electricity generator.
Direct current If you flow the current in only one direction it is c known as direct current or DC. The batteries of the solar cells can supply DC electricity, so typical battery can supply about …show more content…
the main of the electricity it is an AC supply. However, in the UK mains supply can be up to 230V. The frequency of 50Hz (hertz), so this means that it is able to change the direction and back again 50 times in seconds. The diagram which is shown above is oscilloscope screen displaying the signal from AC supply
Use V = IR to predict values in electric circuit investigations.
Potential difference
The potential difference across a component can be calculated using Ohm's Law:
Using the Ohm’s law the potential difference across a component can be calculated.
Potential difference (V) = current (I) x resistance (R)
V = I x R
For example, for I = 25 milliamps (mA) and R = 330 ohms, V = 0.025 x 330 = 8.25 volts Ohm's Law can also be rearranged to identify the current or the resistance:
I = V / R
For example, for V = 9 volts and R = 330 ohms, I = 9 / 330 = 27 mA For example, for V = 9 volts and I = 18 mA, R = 9 / 0.018 = 500 ohms
In a practical you can use an ammeter and a voltmeter to check the values you calculated for a circuit using ohms law

But then the steam powers a turbine which is able to spins a huge magnet inside a copper wire and the heat gives energy converts to a mechanical energy which is converted to electrical energy in to the generator. Then electricity flows from the power plant through wires to the step up transformer and then the transformer raises the pressure so it can travel long distances and then it raised as high as 756,000 volts.
Electric current then it runs through the power lines to the substation transformer where the pressure is lowered to between 2000 and 13000 volts.
Then the electricity is taken through the lines to a pole transformer and a transformer box if underground and the pressure is lowered again to between 120 240 volts.
Then from this side on the electricity comes into our homes through a service box and then the meter is located which can measure how much electricity we use in our homes and the wires take the electricity around our homes powering the lights and all our other
