Three ammeters measure the currents in separate parts of the circuit illustrated. The diagram shows the readings on the ammeters. How can we tell that at least one of the ammeters must be faulty?
- AAll three ammeters must read the same value.
- BAll the current takes the easier path through the $6\,\Omega$ resistor.
- CThe current from the battery must be equal to the sum of the currents in the two resistors.
- DThe current in the two parallel resistors must be the same.
