Question

Circuit B has battery voltage V0= 9.0 volts and three identical bulbs. With the switch open, lamp 1 and 2 are in series and the ammeter reads an initial current of 0.60 A?

A. What will voltmeters v1 and v2 read?

B. Determine the power in each lamp with the switch still open, as shown in the diagram. Lamp 1______ Lamp 2______.

C. Now you close the switch so that lamps 2 and 3 are in parallel and in series with the lamp 1. What current will the ammeter read now?

D. What will voltmeters V1 and V2 read now?

E. Will the lamp 1 be brighter, dimmer or the same as before you closed the switch?

F. Will lamp 2 be brighter,dimmer or the same as before you closed the switch? Explain

G. Calculate the  power in each lamp after closing the switch ? Lamp 1___ Lamp 2 _____    Lamp 3 _____
