How to use a multimeter to measure the resistance of a wire? Do you use the meter to measure the resistance of a wire?

Because the resistance of the wire is relatively small, the ordinary multimeter can not measure out, because the accuracy is not enough, in order to measure the resistance of the wire, you can choose a more accurate megohmmeter than the ordinary multimeter

How to measure the insulation resistance and grounding resistance of two wires with a multimeter?

With a multimeter, you can only estimate it roughly. First, the conductor is not charged. Then, adjust the multimeter to the resistance gear. The resistance is adjusted to the maximum gear, which is usually x10k gear. Zero gear. Connect the red and black pens to the two wires to be measured respectively. The reading is the insulation resistance of the two wires. Generally, it is almost full scale, indicating infinite resistance

How to measure the resistance of a coil of copper wire? Have you ever used it with a digital multimeter? What's the reason for the instability of the number at 200 ohm?

Commonly used. The unstable number is caused by the unstable contact between the multimeter and the wire under test. When you hold the multimeter firmly and the contact is stable, a more stable indicator will appear. However, when the battery of the multimeter is old, it will also be unstable. At this time, it shows that the contact is very stable and the indicator is still getting smaller, It is possible to get more accurate and stable values

What's the size of the wire

First of all, the current value of load power should be calculated to select the size of wire
Safety interception of wire:
2.5 square 4 square 6 square 10 square
Copper core. 23a 31a 40A 57A
Aluminium core wire. 18a 24a 31a 44a
Select the current value of the wire greater than the load power
