The diagram shows 2 coils, P & Q. aligned along their central axes. Each with a larger number of turns. R Coil P is connected to an EMF and a switch, as shown. The resistor is only present to limit the current and prevent damage to the circuit. Coil Q is connected to a ammeter (A), which measures current flow. What will happen when the switch is closed?
The ammeter will show a momentary spike in current, then drop back to zero. it will not measure a current unless a battery is connected to it Coil Q will produce a magnetic field that points in the same direction as the one produced by coil P. The ammeter will show a spike in current that will be maintained as long as the switch connected to coil P remains closed. it will never measure a current w
