[Rhodes22-list] Strange Electrical Problem

[Lowe, Rob]

Graham,
Low current would be a result of a high load (high resistance).  Basic electricity is V=IR where V is the voltage (in volts), I is the current (amps) and R is the resistance (ohms).  Of the three, voltage is the easiest to measure if you have a volt meter.  Rearrange the equation for current.
I = V/R.  If you have low or no current for a given voltage you have high resistance (open circuit, blown fuse, corroded connection, bad motor, etc.).
Current is more difficult to test for.  In a DC circuit you need to insert your meter into the circuit.  Better to measure the voltage of the source, measure the resistance of the load (power off, circuit open) and compute the current.

Might someone explain how a current would show expected voltage (ie, 120
volts) but low current? Why would that occur and how would you test for
that? How would you know what the current should be?

Thanks,

Todd,

Thanks for that suggestion...I may redo the leads to eliminate them as the
source of this problem.
