You say you have a bad history with batteries & cables ?

Here you go Ernie.....


To make a current flow through a resistance there must be a voltage across that resistance. Ohm's Law shows the relationship between the voltage (V), current (I) and resistance (R). It can be written in three ways:
V = I × R or
I = V/R
or
R = V/I

where:
V = voltage in volts (V)
I = current in amps (A)
R = resistance in ohms (R)
or:
V = voltage in volts (V)
I = current in milliamps (mA)
R = resistance in kilohms (k)
