Question

1.) The lightbulb in the circuit diagram of (Figure 1) has a resistance of 0.90 ? . Consider the potential difference between pairs of points in the figure. Suppose that E = 3.5 V .

Part A.

What is the magnitude of ?V12?

Express your answer with the appropriate units.

Part B

What is the magnitude of ?V23?

Express your answer with the appropriate units.

Part C

What is the magnitude of ?V34?

Express your answer with the appropriate units.

Part D

What is the magnitude of ?V12 if the bulb is removed from the socket (i.e. the circuit is not closed)?

Express your answer with the appropriate units.

Part E

What is the magnitude of ?V23 if the bulb is removed from the socket (i.e. the circuit is not closed)?

Express your answer with the appropriate units.

Part F

What is the magnitude of ?V34 if the bulb is removed from the socket (i.e. the circuit is not closed)?

Express your answer with the appropriate units.

Part G

Opt D. (wouldnt fit in picture)

Explanation / Answer

Req = 2.9 ohm

I = V/Req = 3.5/2.9

part a )

V12 = I*R = 2.41 V

part b )

V23 = I*R = 1.086 V

part c )

V34 = 0 , ( no resistancein wire )

part d )

if circuit is open

V12 = 0

part e )

V23 = 3.5 V

part f )

V34 = 0

part g )

B option
