rain + ice bump together = knock of electrons
top of cloud = positively charged
bottom of cloud = negatively charged
huge voltage and MASSIVE spark
Current - flow of electrons - AMPERE, A.
voltage - driving force that pushes current around, Electrical pressure - VOLT, V.
resistance -SLOWS things down - OHM, .
increased voltage = MORE CURRENT.
increase resistance = LESS CURRENT.
measures current - AMPS.
must be in series!
never in parralel!
measures voltage - volts.
must be in parallel!
RESISTANCE = POTENTIAL DIFFERENCE / CURRENT
