Question

1. Did the resistance of the tungsten filament in the light it got hotter'? 2. Three resistors are connected in a series circuit as shown. R1 > R2> R3 Which of the resistors has the largest current through it? 3. Which of the resistors has the largest voltage drop across it? Three resistors are connected in a series-parallel circuit as shown. R1 R2 > R3 Which potential diference would be greater, the voltage across R2 or V the voltage across R3? Explain. 4. RI R3 5. Which of the resistors has the largest voltage drop across it? Name Signature Date EXP 2 Page 18

Explanation / Answer

1) when temperature increases resistance of a filament also increases.

2) in a circuit resistors are in series so all the resistors have same current

3) across R1 only more voltage should be drop based on ohms law V=iR

4) R2,R3 are in parallel so both are having same voltage.

5) across R1 only more voltage is drop. because R1 nad combination of R2 nad R3 ARE IN SERIES

4)
