Resistance And Potential Difference Flashcards
1
Q
What is the formula for potential difference
A
Current x resistance
2
Q
What can affect the resistance of W circuit
A
Whether components are in series
Or
Parallel
3
Q
Where should the ammeter be placed
A
Measure the current (amps) flowing through the test wire
The ammeter must always be placed in series with whatever you’re investigating
4
Q
Where should the voltmeter be placed
A
Measures the potential difference across the test wire in (volts)
Should be placed in parallel around whatever you’re investigating
