## What device measures DC current?

ammeter, instrument for measuring either direct or alternating electric current, in amperes.

Which instrument is used for DC measurement only?

Permanent Magnet Moving Coil (PMMC)
Permanent Magnet Moving Coil (PMMC) is only used for DC measurements. Moving Iron (MI) type instruments can be used for both AC & DC measurements.

### What device use direct current?

Devices that use batteries get their energy from direct current. They are powered by this kind of electricity. Flashlights and cameras are examples of devices that use direct electric current.

What are the measuring devices for current?

Instruments such as digital multimeters, current probes, and clamp meters are often used to measure current.

#### Which instrument is used to measure both AC and DC?

ammeter
A multimeter can be used as a voltmeter (to measure voltage), an ammeter (to measure current, both DC and AC) and an ohmmeter (to measure resistance).

Why does PMMC measure DC?

PMMC instruments are only used for measuring the DC quantities and it gives the average of value of the quantity being measured. If we apply AC current to these types of instruments, the direction of current will be reversed during negative half cycle.

## What are DC devices?

Direct current is used in any electronic device with a battery for a power source. It is also used to charge batteries, so rechargeable devices like laptops and cell phones come with an AC adapter that converts alternating current to direct current.

What is an example of a direct current?

Direct current is produced by rectifiers, batteries, generators with commutators, and fuel cells. For example, the current flowing in appliances running on batteries or in a flashlight is a direct current. The most common use and essentiality of direct current is electroplating.

### What is the name of measuring instrument?

Vernier Caliper Vernier Caliper is a widely used linear measurement instrument with the least count of 0.02 mm. It is used to measure linear dimensions like length, diameter, depth. The main scale and the Vernier scale can slide along the main scale.
