A circuit is constructed from two batteries and two wires, as shown in the diagram below.

Each battery has an emf of 1.3 volts. Each wire is 27 cm long, and has a diameter of 0.0007 meters. The wires are made of a metal which has 7e+28 mobile electrons per cubic meter; the electron mobility is 5e-05 (m/s)/(V/m). A steady current runs through the circuit. The locations marked by "x" and labeled by a letter are in the interior of the wire.

1.What is the magnitude of the electric field at location F?

EF= ________ V/m

2.How many electrons per second enter the positive end of battery #2?
__________electrons/s

3.If the cross-sectional area of both wires were increased by a factor of 2, what would the magnitude of the electric field be at location F?
new value of EF = ________V/m

the circuit shown below is made using identical bulbs and an ideal battery.

a)Which of the following statements is correct? Explain your reasoning for the choices you have made.

Bulb D is brighter than bulb F.

Bulb D is dimmer than bulb F.

Bulbs D and F have the same brightness.

There is not enough information given to compare the brightness of two bulbs.

b)Bulb D in the circuit above is then removed from its socket. (What happens when a bulb is removed? Study the description of a bulb's construction on page 2 of the Electric Circuits I: Current lab if you are unsure.) When bulb D is removed from its socket

the brightness of bulb F would:

- Increase

- Decrease

- Stay the same

- Not enough information
