Module – 7 Eng.Islam Al-Jarrah

 Define energy.  Differentiate between the different forms of energy.  Draw energy transfer diagrams.  Give examples of electrical machines.  Define the purpose of motors and generators.  State the function of a capacitor.  State the purpose of a Power Distribution Network.  Conduct practical tasks to demonstrate the application of motors, generators, and capacitors. Eng.Islam Al-Jarrah

What is energy? What do you know about Energy? Eng.Islam Al-Jarrah

 Energy can be changed or transferred from one form to another Eng.Islam Al-Jarrah

What is Electrical Energy? Examples on Electrical Energy!! Eng.Islam Al-Jarrah

 Electrical energy is delivered by tiny charged particles called electrons, typically moving through a wire.  Electrical energy is what is stored in a battery, and can be used to power a cell phone or start a car. Eng.Islam Al-Jarrah

 Electrical machine is a device that converts either mechanical energy to electrical energy or vice versa.  Motors and generators are examples of electrical machines. Eng.Islam Al-Jarrah

 If a motor is connected to a battery, the motor will turn. Here it converts electrical energy to kinetic energy.  A motor can also be used to generate electricity, so it is called a generator or a dynamo.  Electricity is generated when the axle of the motor is turned. Eng.Islam Al-Jarrah

 A capacitor is a device that could be used to store electrical energy.  When the capacitor is discharged (empty), both the plates will have no charge. Eng.Islam Al-Jarrah
