These basic principles of electricity are the basis for the electric devices found in your home and school \u2014 things like digital cameras, stereos, flashlights, calculators and portable CD players.
Ohms and Volts<\/p>

Scientists know that there are ways of measuring electrical quantities. One of these is coulombs per second<\/strong>, a measure of the flow of electrons through a metal conductor or wire. A current of one coulomb per second equals one ampere.<\/strong><\/p>

Even materials that conduct electricity resist the flow of electrons. The unit of electrical resistance is an ohm.<\/strong> The pressure needed to make one coulomb per second (one ampere) flow through a conductor having a resistance of one ohm<\/strong> is one volt.<\/strong><\/p>

Ohm\u2019s Law explains the relationships between voltage (E), resistance (R), and current (I).<\/p>

In two circuits of equal voltage, the current will be proportionately greater in the circuit of lower resistance. In circuits of equal resistance, the current flowing will be directly proportional to the voltage applied. Current is directly proportional to voltage, inversely proportional to resistance.<\/p>

I (Amperes) = E (Volts)\/R (Ohms)<\/p>

Also: E = IR or R = E\/I<\/p>

One of the most common electrical measurements you\u2019ll use is the watt, a unit of electrical power: W (Watts) = E (Volts) x I (Amperes).<\/p>

The quantity of electric charge is measured in coulombs.<\/p>

Scientists and engineers use their knowledge of electricity to design the latest instruments, tools and devices. And you can put the principles of electricity you\u2019ve just learned to work with the science of batteries brought to you by Energizer.<\/p>

Please Read Carefully!<\/p>

All experiments use safe, low-voltage battery power. Household electrical current contains high voltage that could cause serious injury. DO NOT use household electrical current for any of these experiments. ALL experiments should be conducted under adult supervision.<\/p>

  • Carefully follow wiring instructions for each experiment. Improper wiring can result in battery leakage and\/or rupture.<\/li>
  • DO NOT take a battery apart. Contact with internal battery material can cause injury.<\/li>
  • DO NOT dispose in fire, recharge, put in backwards, or mix with used or other battery types.<\/li><\/ul>

    This may cause batteries to explode, leak and cause personal injury.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
