How to use normal multimeter to measure high AC current.


A general cheap analog multimeters will not have directly AC current ranges.  But we are an Electric Appliance Repair, will always have this problem. For example: Measuring current of the electric appliances.

How to use normal multimeter to measure high AC current

We can modify the multimeter on AC 10V range to measure AC current 0-10A,use a 1 ohms resistors in palleral to lead of meter. The resistor must withstand power (watts) is adequate,do not burn while measured.

How to find the power of resistors.
The current of circuit,squared then multiply by 2, to the safety of its use. Current value is about 2A is a resistor value that is equal to 8 watts (2x2x2). Add to that the resistor will measure current less than 10A. Which is the highest on the scale. If you want to measure more than this to reduce the resistance to the other. While the measure has to be careful not to resistors in parallel, then dropped it. Otherwise, the meter will be damaged
