Can an ammeter with a resistance of 0.02 Ohm, designed for a maximum current of 10 A

Can an ammeter with a resistance of 0.02 Ohm, designed for a maximum current of 10 A, be connected directly to a battery, the voltage at the poles of which is 2 V?

Given:

R = 0.02 Ohm – resistance of the ammeter;

Imax = 10 Amperes – the maximum current for which the ammeter is designed;

U = 2 Volts – voltage at the battery poles.

It is required to determine if the ammeter can be connected to the battery.

Let’s find the current that will be in the circuit when the ammeter is connected to the battery:

I = U / R = 2 / 0.02 = 100 Amperes.

Since I> Imax (100> 10), the ammeter cannot be connected to the battery.

Answer: The ammeter cannot be connected directly to the battery.
