Quiz designed for Mrs. Robinson's students who are attempting the 3 credit Unit Standard in Electricity.
If one lamp breaks, the other will shine more brightly.
If a voltmeter shows the voltage across the first lamp to be 3 volts, we can assume the voltage across the second lamp will be 1 volt.
The voltage across each lamp will be 4V, just like the voltage across the battery.
If we attach voltmeters across the two lamps, both voltmeters will read '12V'.
If we attach ammeters across the two lamps, both meters will will read '12V'.
If we attach another lamp and voltmeter in parallel, the third voltmeter will read '12V' too.
The first voltmeter will read 6V; the second will read 3V
The first voltmeter will read 3V; the second will read 6V
Both voltmeters will read 3V
Both voltmeters will read 6V
The CURRENT (Amps) will be the same at any point in the circuit
The CURRENT will be higher at the end of the circuit
The CURRENT will be lower at the end of the circuit
The number of Amps shown by an ammeter placed right after the power source would be the same as the Amps in each part of the circuit
The Amps in each parallel wire of the circuit would be equal
The Amps in each parallel wire of the circuit would add up to the Amps shown by an ammeter put in directly after the power source
If A1 reads 6A, A2 and A3 and A4 will each read 2A
If A1 reads 6A, A2 will read 3A, A3 will read 2A, and A4 will read 1A
If A1 reads 6A, all the other ammeters will read 6A as well
If A1 reads 6A, the readings on the other three ammeters will add up to 6A; for example, they could read A2=2A, A3 = 2A, A4 = 2A
If A1 reads 8A, the reading on A2 will be 8A and the reading on each of the other two ammeters will be 4A
If A1 reads 6A, the readings on the other three ammeters will add up to 6A; for example, they could read A1=2A, A2 = 2A, A3 = 2A
