Introduction: This project is one of the most famous electricity projects that can be performed successfully by most students in the age of 10 to 16. It helps students to learn about producing electrical energy using chemical energy. Since the same method is used to get energy from many fruits and chemicals‚ this project has many names. Following are some of the other names or titles for this project: |Fruit power or fruit battery

for watches. Cells force electrons to flow along conductors.(DK Science 150). "The electrical force of a cell or battery is called its electromotive force (emf). This force‚ which makes electrons flow around a circuit‚ is measured in units called volts (v). Each king of cell has a particular emf. A dry cell‚ for example‚ has an emf of 1.5volts." (DK science 150) The other way to measure a battery is by how much current it can provide. Current is used to measure how many electrons flow through the

This is because the higher the voltage‚ the stronger the energy produced in the coil around the metal rod. EXPERIMENT (PROCEDURE): Materials used: 6 volt battery Coils Partner(s) to hold coil and metal rod/battery Metal rod Paperclips Worksheet to record data There are eight steps to the procedure: Get a 6 volt battery Get a long or short coil depending on your trial Get metal rod Get paperclips Wrap coil around metal rod (10‚ 20‚ 30‚ 40 or 50 times for

resistor board -Extech instruments (0-18 Volts) Power Supply Procedure: A circuit connecting the resistor board‚ the voltmeter and the milli-ammeter is assembled. The 20 milli-ampere range is selected on the ammeter and the 20V on the voltmeter. The power cord is then plugged into an electrical outlet and the unit is turned on. The experiment begins at 15 volts. The voltage and current are both recorded and these steps are repeated successively in two volt increments. A graph of I as a function of

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 the flow of electrons. Changing the shape or choosing different materials with different resistance are ways that they do this. A resistor

An experiment to investigate the factors which affect Resistance in a wire What is resistance? A potential difference (V) applied across a wire of length (l)‚ there is in the conductor‚ an electric field (E). In this electric field the free electrons are not however under continuous acceleration (Ee/m). This is because they repeatedly collide with the moderately massive vibrating atoms losing their kinetic energy. The vibrating atoms having gained this kinetic energy now vibrate more. The resulting

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
