Both “Before You Were Mine” by Carol Ann Duffy and “Mother Any Distance” by Simon Armitage focus on the role of being a mother and having to give up something. In “Before You Were Mine” its Carol Ann Duffy’s mother letting go and giving up her carefree lifestyle‚ to take up the important role of a mother. Whereas in “Mother Any Distance” its Simon Armitage’s mother realising she has to let her son grow up and leave her grasps. The poem “Before You Were Mine” by Carol Ann Duffy‚ focuses on the fact

pile was made of two electrodes of zinc and copper and sulphuric acid as the electrolyte. His name is used as the SI unit of electric potential. The volt is named after him in honour of making the first chemical battery. The Ohm Georg Simon Ohm was the father of the Ohm. He was born in Bavaria and taught at a lot of universities and schools. While he was teaching at a bad school in Bamberg‚ he decided to prove that he was better than that by writing a geometry book. He later went onto‚ in 1827

to drop the voltage of the current as it flows from one terminal to the other. Resistors are primarily used to create and maintain known safe currents within electrical components. Resistance is measured in ohms‚ after Ohm’s law. The Resistance was discovered by the year 1827 from Georg Simon Ohm‚ a German electrician. RESISTANCE BOX 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

Chapter I I. Introduction Power electronics converters can be found wherever there is a need to change voltage‚ current of frequency of electric power. The power range of these converters is forming some mill watts (as in mobile phone) to thousands of megawatts in an HVDC transmission system. With classical electronics‚ electrical currents‚ and voltage are used to carry information‚ where as with power electronics‚ they carry power electronics becomes the efficiency An inverter converts DC

ALL ABOUT AMPERE MACHINE ABEGAIL LALOMA CARLA DUMALE AMPERE Metric (SI) unit of electrical current. One ampere is the amount of current flowing with an electromotive force of one Volt in a circuit having a resistance of one Ohm. Named after the French mathematician and physicists Andre Marie Ampere who discovered the basic laws of electromagnetism. AMPERE’S FORCE LAW Ampere’s force law states that there is an attractive or repulsive force between two parallel wires carrying an electric

coding resistance was furthest off. Introduction: Georg Simon Ohm established that current (I) in a wire is proportional to the voltage (V) applied to its ends. How much current flows in the wire depends on the voltage but also on the resistance (R) of the wire. A higher resistance yields a lower current for a given voltage. (I= V/R) This is known as Ohm’s Law‚ where V is measured in volts‚ I is measured in amperes‚ and R is measured in ohms. Electrical engineers have to build devices that control

HISTORY OF ELECTRICITY Depite what you have learned‚ Benjamin Franklin did not "invent" electricity. In fact‚ electricity did not begin when Benjamin Franklin at when he flew his kite during a thunderstorm or when light bulbs were installed in houses all around the world. The truth is that electricity has always been around because it naturally exists in the world. Lightning‚ for instance‚ is simply a flow of electrons between the ground and the clouds. When you touch something and get a shock

Electricity is important in our everyday lives. It is essential for almost everything in our modern world. The knowledge learned in the past about electricity enabled such things as engines‚ telephones‚ radios‚ computers‚ and much‚ much more. As early as 600 B.C.‚ the Greeks were already studying electricity. They noticed that if you rubbed a piece of amber with fur‚ it had a charge with the ability to attract small objects. Many years later‚ in the 16th Century‚ William Gilbert discovered many

enamel‚ or covered in molded plastic to protect them. Because they are often too small to be written on‚ a standardized color-coding system is used to identify them. The first three colors represent ohm value‚ and a fourth indicates the tolerance‚ or how close by percentage the resistor is to its ohm value. This is important for two reasons: the nature of its construction is imprecise‚ and if used above its maximum current‚ the value can change or the unit itself can burn up. • RESISTANCE
