 Negative particles are called? Electrons Positive particles are called? Protons Neutral atomic particles are called? Neutrons Opposite electrical forces do what? Attract Name of anything that turns electrical energy into another form of energy. Resistor Current of electricity through a circuit is measured in? Amperes The push/pull in a power supply measured by the potential motion of electrons is called? Voltage Ampres (I) can be found by dividing voltage by what? Resistance The Power or Heat drawn by a resistor measures in watts can be found by multiplying the square of ____ times resistance? Current Amps multiplied by Voltage equals what? Watts Voltage squared divided by resistance equals? Power in Watts The total resistance of a series circuit is found how? R1+R2+Rn The total resistance of a parallel circuit is found how? 1 _____________________ = R total ((1/R1)+(1/R2)+(1/Rn) As resistors are added in parallel the total resistance: increases or decreases? Decreases Things that are good heat conductors are generally: good or bad electrical conductors? Good If you wanted to build up a large electrostatic shock where could you best do this: Arizona or Florida? Arizona. A bird on a high voltage power line. A girl with long arms grabs the line. Why does the bird live? Why does the girl die? The girl provides the current a path to the ground. The bird does not. Batteries convert _____ energy into ____ energy. Choices: Chemical, Kinetic, Electrical, Mechanical, Potential Chemical to Electrical Name the electrolyte, anode and cathode materials of a lead acid battery during discharge. Electrolyte = Sul. Acid H2SO4 Anode = lead Cathode = lead oxide Inside a cell electrons flow from the _____ to the _____? anode cathode cathode to anode anode means the electrons move (towards or away) from a specified terminal? away Explain fuel cell. A fuel cell converts oxygen and hydrogen into water harnessing the direct current produced in the process. Oxygen or Hydrogen looses an electrons in a Hydrogen Fuel Cell. Hydrogen 2H2 => 4H+ + 4e- Current flows towards or away the positive terminal? Away Electrons flow towards or away the positive terminal? Towards Current passing through a coil induces a right or left hand magnetic field? Right Hand Motors need an alternating or direct current to operate? Alternating Motors turn _____ energy into ____ energy. electrical into mechanical Generators turn ____energy into ____ energy. Mechanical into Electrical Energy. An alternating magnetic field in a loop will cause _______? A Current
