electrical system
movement of charged electrons through wires
volts
this is the measurement of voltage
voltage(V)
voltage is the potential for charge to move
current(I)
the amount of charge flow
amps
measurement of charge flows
resistance(R)
the wires opposition to flow
ohms
measurement of resistence
ground is represented by
three lines represent this
ohms law
V=IR
switch
an electronic device that acts like a wire between two terminals if the switch is “on”
electronically controlled switch
a switch that also requires power
examples of switches
relay, vacuum tube, discrete transistor, integrated circuit…
transistor
a smaller simpler switch with no mechanical switch
cMOS technology
uses pMOS and nMOS transistors to implement digital curcuits
nMOS transistor
conducts when its control input is 1
