Physics measures what is measured in amps

Measure current / amperage

How can one measure the amperage or the current? We deal with exactly these questions in this article and provide you with a corresponding example and a suitable drawing. This article belongs to the field of physics or electrical engineering.

Whether in the lectures on physics, electrical engineering or measurement technology. Often one is interested in how much current flows in a circuit. So-called ammeters or ammeters are used to measure this. The following two drawings show a before-after for the circuit. This is explained in more detail below.

Before the measurement:

With measuring device:

Measure direct current

To measure direct current, you have to do the following:

  1. Set the largest measuring range for a current measurement (direct current).
  2. Connect the meter in series. The negative pole of the voltage source should be connected to the negative pole of the measuring device. As a result, the positive pole of the voltage source is also connected to the positive pole of the measuring device.
  3. Then switch the measuring range down so that the pointer is in the middle to right area of ​​the display.
  4. Read the current strength (taking into account the measuring range).

Measure alternating current

To measure alternating current, you have to do the following:

  1. Set the largest measuring range for a current measurement (alternating current).
  2. Connect the meter in series. The polarity does not matter in this case.
  3. Then switch the measuring range down so that the pointer is in the middle to right area of ​​the display.
  4. Read the current strength (taking into account the measuring range).
