How do you measure DC amp output from rectifier unit?

You can use a DC ammeter.


To increase the range of a dc ammeter you would use a?

To increase the range of an ammeter, you connect a very low impedance resistor in parallel with the ammeter.


A DC wattmeter essentially consist of?

power i.e current and voltage or ammeter and voltmeter


What is a DC ammeter and how does a DC ammeter work?

An ammeter is an instrument designed to measure electric current, which is expressed in amperes. A d.c. ammeter is one that will measure direct current (d.c.), as opposed to alternating current (a.c.). Ammeters are rarely used outside laboratories. Instead, multimeters are more commonly-used, and these will measure d.c. or a.c current and voltage, together with resistance. In other words, a multimeter functions as an ammeter, a voltmeter, and an ohmmeter. The principle of operation of a digital ammeter is too complicated to explain in this forum. An analogue ammeter works by a rotating coil to which is attached a pointer. The coil is balanced between two hairsprings and located between opposite faces of a permanent magnet. When current passes through the coil, the resulting magnetic field reacts with the permanent magnetic field, causing the coil to rotate, tightening the hairsprings. When the torque due to the current matches the opposing torque due to the hairsprings, the coil will stop turning. The position of the pointer on a scale will then indicate the current passing through the ammeter.


Can you use ac ammeter to measure dc current?

It depends. If it's an inductive ammeter (the kind that clamps around a wire), it won't work at all. If it is the type of ammeter that is actually placed in the circuit, it will work but it won't be accurate.CommentActually, modern 'clamp on' ammeters WILL measure d.c. currents. It uses the Hall Effect to measure the current.

Can DC ampere be measured with AC amp meter?

No. The ammeter must be designed to measure DC. Some clamp-on ammeters are designed to measure both AC and DC.
