Question
circuit is constructed from two batteries and two wires, as shown in the dagram below Battery 1 Battery 2 has an emf of 1.3 volts. Each wire is 23 cm long, tron mobility is 3e o5 (m/s)/(V/m). A steady current runs through the circuit 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 locations marked by and labeled by a letter are in the intersor of Which of these statements about the electric field in the interior of the wires, at the locations marked by s, are true? Check all that apply D At every marked location the magnitude of the electric field is the same. At location D the electric field points to the right The magnitude of the electric field at location D is larger than the magnitude of the electric field at location C. Which of the following equations is a correct energy conservation (round-trip potential difference) equation for this circuit, along a round trip path starting at the negative end of battery #1 and traveing counterclockwise through the circuit (that is, traveling to the left through the battery, and contrurg on rond t-crcat n the tar- direction)7 O +1.3V-E(o.23 m)+1.V- E (o.23 m) 0 .1.3 V + E"(0.23 m) O +1.3V E (0.23 m)-Explanation / Answer
1.
2.
Applying Kirchoff;s Loop rule
1.3-E(0.23)+1.3 -E(0.23) =0
3)
0.46EB=2.6
EB=5.652 V/m
4)
I=(7*1028)(pi*(7*10-4/2)2)(3*10-5)*5.652
I=4.568*1018 electrons/s
5)
Electric field does not depend cross-sectional area ,Electric field at location B remains constant
EB=5.652 V/m
6)
Answer is "C"
