HOPEFULLY HELPFUL?? Feel free to use and edit to perfection…. If there is anything missed or the order is wrong, JUST MAKE IT BETTER!!!
• A series circuit - is where the components follow each other in a circle.
• A parallel circuit involves electrical components that are arranged side by side, so that if one is not working, the others will still function
• Current (I) - refers to the amount of electrical charge that flows through a conductor in a given time. The unit for current is the ampere (A). Current is measure with an ammeter.
• Resistance (R) - resistance refers to the opposition to the flow of electricity through a conductor. The unit for resistance is the Ohm (Ώ)
• Voltage (V) - a measure of the difference in potential between two points on a circuit. Often referred to as potential difference. The unit for voltage is the volt (V).
• Watt - the amount of energy. Wattage is the unit used to measure power.
• Ohm's law - for a given conductor, the ratio of voltage to current is a constant number called the electrical resistance. V/I = R
• Atoms with empty spaces in the outermost electron bands are conductors.
• Atoms with a full outside track which is far from the next empty track are insulators
• You can generate electrical energy by moving or spinning a conductor within a magnetic field (or vice versa) continuously.
• Current is the movement of electrical charge.
• A large current has more electrons moving through an area at a time than a small current.
• An ampere is the unit used to measure the speed of a current.
• A coulomb is a group of 6.25 x 1018 charges.
• An ampere is the speed of one coulomb passing by in one second.
• An ammeter measures the speed of a current in amperes.
• Conventional current is the path from the positive terminal to the negative terminal. Most currents flow against the conventional direction.
• Voltage is the unit used to measure electrical pressure.
• Voltage only occurs when there is an imbalance of electrons.
• A voltmeter measures the amount of energy available to move between two points.
• A conductor is a substance that allows a current to flow through it readily.
• Good conductors include many metals and ionic solutions such as salt water.
• An insulator is a substance that prevents a current from flowing.
• Good insulators include many plastics, glass and carbon-based materials.
that page is great
I agree with drew!!!
