Amp Tester
HOW MUCH CURRENT A HOME OUTLET HAS? NOTE: PHILIPPINE SETTING.?
A. If a home outlet has 220volts ac, how much current present on it?
a. 1 amp
b. 5 amps
c. 10 amps
d. or how much is it exactly?
B. In the absence of a multi-tester, how can i know if my home outlet with 220vac contains how many current?
C. If for example, a home outlet with 220vac contains 10amps:
a. if i plug a 220 to 110 stepdown transformer to that outlet, does it mean that the transformer output current will be 20amps? or 183amps for a 220 to 12vac stepdown transformer?
Thanks!!! Thanks!!! Thanks in advance!!!!
A. No current flows unless a load is present, that is, until you’ve plugged an appliance into that outlet and turned it on.
B. Again, there must be a load for current to flow. If you do have a load and know the resistance of the load then the current = V/R = 220V/R. Inductive devices such as motors of course have both resistance and reactance so current will be a different matter from a purely resistive load.
C. For a transformer: power input = power output. Thus 220 x 10A = 110V x 20A.
I think you may asking the rated ampacity of the outlet which is a different matter.
