The ammeter must be connected in series in the circuit to be measured. Under what circumstances is the ammeter connected in parallel in the circuit to be measured? Please use the circuit diagram. Also, I said in my book that the ammeter can't be directly connected in parallel with the consumer or ammeter. What's the circuit diagram in this case?

When an ammeter is used as a voltmeter, it needs a very large resistance

How to measure DC current with clamp ammeter?
It is well known that the clamp ammeter can measure AC current, but some people say that the clamp ammeter can also measure DC current, and take out the measuring tool, fluke's, just like the ordinary clamp ammeter, its shape is a little smaller
I don't know what the principle is. I need a man of insight to answer it

DC current is based on the working principle of Hall element: the so-called Hall effect refers to the physical phenomenon of transverse potential difference when the magnetic field acts on the carriers in current carrying metal conductors and semiconductors. That is to say, the current is determined according to the strength of the magnetic field

What current can a clamp ammeter measure

If you look at the manual, most clamp ammeters can measure alternating current, some can measure direct current, and some professional meters can be used for both AC and direct current
