An ammeter with a full scale deflection for i 140 a has an


An ammeter with a full scale deflection for I = 14.0 A has an internal resistance of 21.0 ohms. We need to use this ammeter to measure currents up to 16.0 A. Use a resistor to protect the ammeter.

What size resistor do you need to connect to the ammeter, and should it be in series or parallel?
