Can multimeter measure the breaking and closing of circuits by measuring resistance?
Measure the loop resistance with a multimeter and determine whether or not the short-circuit depends on the loop resistance. Home power is best to switch all the switches on and unplug them with electrical appliances. Electronic circuits may be more complex, high power appliances or small resistors do not interfere with your judgment.
Measurement of short circuit problem is not simple, especially the multimeter internal battery voltage is low, the problem of short circuit measurement of household electricity need extra attention, short of some bad contact may haunt measurement problem, but also on the electric circuit.
Using 200 ohm gear, you can roughly measure on-off, less than 10 ohm, usually short circuit.
In general, all meters are labeled as a diode, and a buzzer can be heard in the short circuit. In engineering, it is usually used to measure the on-off of a circuit.Of course, it is also possible to measure the line resistance by measuring resistance. In general, 5 ohms below can be considered to be conducting, and greater than 10 ohms can be considered to be disconnected.You'd better send up a picture and show them to you.
