Here's a taster:

Equations
· Current = Charge/Time or = Charge/Volt
· Charge = Current * Volts
· Volt= Energy/Charge
· Resistance = Current/Volt
· Total Resistance:
· In a series: Total Resistance = R1+R2
· In a parallel: 1/Total Resistance = 1/R1+1/R2
· Energy transformed = Potential difference *
Current * time…read more

Here's a taster:

Current vs Voltage
· In a series:
· Current is the same at any point
· Voltage splits up over each component
· In a parallel:
· Splits at junctions in the current
· Voltage is the same across each "strand"…read more
