Chapter 22:Electricity Section 1:Electric Charge Section 2: Electric Current
Static Charge
Solid
due to transfer or electrons
Solution
due to transfer by ions
Protons
positively charged
induced charge
separation of positive and negative charges on a fields
static electricity
Electrons
negatively charged
atoms
electrically neutral
ions
sharing of electrons
grounding
earth is like a huge conductor
example: lightning rods
electric discharge
rapid movement of excess charge from one place to another
example: electric storm
lightning
conductor
transfers heat easily
metals
gold
copper
aluminum
insulator
dosn't transfer heat easily
rubber
plastic
wood
glass
electric field
electric force
attractive
repulsive
all charged objects exert force on each other.
Electric Circuit
one direction
wire connected to a battery
electric field
electrons move to the positive charge
after a collision, electrons continue to move to the positive terminal
Electric Charge
flows through a circuit
battery
Voltage
Increases as more electrical energy is available
Measured in Volts(V)
converts chemical energy to electric potential energy
Electric Currents
Measured in Amperes (A)
Resistance
The measure of how difficult it is for electrons to flow through a material
Measured in Ohm's
Depends on length and thickness of the wire as well as the material it's made of
Thinner wires have more resistance
Smaller wires have less resistance
Conductors
Mretals
Filaments
Insulators have more resistance than conductors
The amount of electrical energy converted into heat and light depends on the resistance of materials in the circuit
