Electricity is analogous to the flow of water.
Three basic factors:
Potential = similar to water pressure or pressure difference, Voltage "V" (volts)
Current = similar to water flow (gallons per minute), Current "I" (amperes)
Resistance = similar to water's resistance to flow, Resistance "R" (ohms or Omega symbol)
Ohm's Law: I = V/R
I = Current, measured in amps
V =voltage, measured in volts
R = resistance, measured in ohms
Series resistances = several resistances in the flow path
To find the effective total resistance, just add them all together
Parallel resistances = parallel paths with different resistances and flow rates in each path
To find the effective total resistance, divide each resistance into the number one, add them together then divide the number one by that total.
