... Next use the VOM to measure the actual resistance for each of the resistors above. Calculate what the current through each resistor should be using its actual resistance and a supply of 2.0 volts. Compare the currents measured with the milliammeter to those calculated from the actual resistance valu ...

If we were to plug a figure for total voltage into an Ohm's Law equation with a figure for individual resistance, the result would not relate accurately to any quantity in the real circuit. This brings us to the second principle of series circuits: the ...
