Answer:

A "resistor" can be connected in "parallel" to the meter

Suppose that an ammeter reads from 1-10 amps.

Now add a resistor in parallel to the ammeter where the resistor has the same value as the resistance of the ammeter - Now the ammeter will read 1-20 amps because only 1/2 the current passes thru the ammeter.
