The use of an ammeter is being discussed. technician a says the ammeter is used to measure current flow. technician b says the ammeter must be connected in parallel to the circuit being tested. who is correct? '

Both the Technician A and Technician B are correct

Explanation:

According to Technician A, an ammeter measures current flow which is correct.

An ammeter is a device which measures the rate of flow of electrons constituting electric current that flows in a circuit.

According to Technician B, Ammeter must be connected in series in an electric circuit which is also correct.

In a circuit with parallel connections, voltage across each branch is same and current is distributed and is different in each branch.

In a series connected circuit, the potential drop, i.e., voltage across each connected element is different while the current in series is the same.

So, in order to measure the correct value of current flowing in the circuit, ammeter must be connected in series in the circuit.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
