if thermo couple ammeter full scale deflection is 10 Amp, for 1/5 th scale what is the Reading?
A thermo couple ammeter full scale deflection is a type of ammeter used to measure electrical current in a circuit. It uses a thermo couple, which is a device that converts thermal energy into electrical energy, to measure the current and display it on a scale.
A thermo couple ammeter works by using the Seebeck effect, where a temperature difference between two dissimilar metals produces a voltage. This voltage is then converted into a current and measured by the ammeter. The higher the current, the higher the deflection on the scale.
Full scale deflection refers to the maximum current that can be measured by the ammeter. This is important because it allows the user to accurately measure the current without damaging the instrument. It also indicates the sensitivity of the ammeter, with higher full scale deflection values indicating a more sensitive instrument.
The full scale deflection of a thermo couple ammeter is determined by the sensitivity of the instrument and the maximum current that it can safely measure. This is usually indicated on the scale of the ammeter or in the instrument's manual.
Yes, there are limitations to using a thermo couple ammeter full scale deflection. These include the maximum current that the ammeter can safely measure, the accuracy of the measurement, and the effect of external factors such as temperature and electromagnetic interference. It is important to understand these limitations and use the ammeter within its specified range for accurate results.
