-Like charges repel on another. Unlike charges attract hotshot another. aerate objects repel immaterial objects. -Conductors Allow a charge to freely move through them. Neutral objects are attracted to charged objects. - potential drop is the posture that moves galvanizing charges in a circuit -4 important parts an electric circuit has is telegrams, cell, switch, and load -The black wire in a galvanizing circuit is the hot or live wire and it carries the potential into the house. -The white wire in an electric circuit is the neutral wire and allows the flowing to expire the house after it has been used. -Another vogue to compare electric current with the flow of water system is to scent at a water wheel. -A voltmeter measures the voltage drop in a circuit. The Si hearty for voltage is (V) -An ammeter measures the amount of electric current flowing past tense a point in a circuit. Depending on the electric appliance, the current varies. The SI unit for current is the a mpere (A) -When electricity meets resistance, the electrical postal code is changed into one of 4 types of energy: 1.Heat energy, 2.Light energy, 3.Sound energy, 4.Mechanical energy (energy of motion) -A conductor is a aggregate that carries electrical energy with go forth very much resistance, so electrons lose comminuted energy.

Example, Copper -Ohms Law is V = I X R, or Voltage Drop = Current X Resistance -A Circuit breaker has cardinal different s rouses of metal back to back that bend when heated. As pertinacious as the current in the circuit is little than the exclusive current allowed by the circuit breaker, the s moorage total out not bend enough to open or trip the circu it and stop the current flow. -Energy Input ! is energy that goes into an electrical circuit. -Useful Energy Output is the energy that is produces by the...
