the flow of electrons
#of electrons per second: 6.25 x 10^8
Potential Difference:aka, definition, units, equation
Resistance: definition, unit, equation
inhibits or impedes electron flow
when the switch is off, no place for electrons to go, electron transportation is incomplete
switch is on, switch connects the ends of open circuit, electrons allowed to flow
electrons flow in ONE direction, ex: battery
electrons have reverse direction, EX: anything plugged in
things that affect resistance of wire
Length(L direct prop to R)
Thickness(R indirect prop to diameter^2)
Composition-exof good:gold, ex bad:nichrome
Temp(T direct to R)
V direct Prop to I, I indirect to R
Series circuit: problems, relation with volts and currents, use, equation
Problems: if 1 goes out-all go out, all appliances must be on 24/7, appliances wont work without proper voltage
relations: volts are shared, current is the same in each resistor
use: blinking lights
Parallel Circuits: reasons to us, relations with volts and currents, equation
Reasons: if 1 goes out-rest are on, dont have to be on 24/7, each appliance gets same voltage
Relations: currents are shared, volts are the same
Final Cost equation
Q=(m)(c)(change in temp)
Info sent as patterns in the controlled flow of electrons thru a circuit
change alt current to direct current, increase signal strenght, turn currents on or off
conduct currents only under certain conditions
combine n-type and p-type
3 layers used as a switch
thin slice of silicon that contain solid state components
