Electricity NEW the BIG idea Moving s transfer energy. 5.1 5.2 Charges can move from one place to another. 5.3 Electric current is a flow of charge.
Electric charge is a property of matter. Electrons have a negative charge.
Electric charge is a property of matter. Protons have a positive charge.
Electric charge is a property of matter. Unlike charges attract.
Electric charge is a property of matter. Like charges repel.
Static charges are caused by the movement of electrons, resulting in an imbalance of positive and negative charges. At first, a balloon and a glass rod each have balanced, neutral charges.
Static charges are caused by the movement of electrons, resulting in an imbalance of positive and negative charges. When they touch, electrons move from the rod to the balloon.
Static charges are caused by the movement of electrons, resulting in an imbalance of positive and negative charges. Afterwards, the balloon has a negative charge, and the rod has a positive charge.
Static charges are caused by the movement of electrons, resulting in an imbalance of positive and negative charges. SIMULATION Learn more about static electricity.
5.2 Charges can move from one place to another. Charge movement is affected by electric potential, measured in volts resistance, measured in ohms A conductor has low resistance. An insulator has high resistance. A ground is the path of least resistance. 3. The ground wire conducts the charge into the ground, where it spreads out and becomes harmless. 1. Lightning strikes the lightning rod, because the rod is the path of least resistance. 2. The rod conducts the charge to a conductor cable, which has low resistance. electric potential volt conductor insulator resistance ohm grounding
5.3 Electric current is a flow of charge. Electric current is measured in amperes, or amps. Ohm's law states that current equals voltage divided by resistance. electric current ampere Ohm s law electric cell Voltage Current = Resistance I = V R Electrochemical cells produce electric current through chemical reactions.
