Question
Question 1 A uniform conducting rod of length 15 cm has a
potential difference across its ends equal to 34 mV
(millivolts). What is the magnitude of the electric field
inside the conductor in units of N/C?
(Reminder: NEVER include units with ANY submission to a
numerical question.)
Question 21 / 1 ptsA cylindrical rod has a length of 73 cm
and a diameter of 1.2 mm. What is the cross-sectional area in
10-6 m2?
Do not include units with your answer.
Question 30.5 / 0.5 ptsFor our four-wire resistors (pictured
below) the voltage is measured across which two terminals (numbered
1-4 in the figure)?
1 and 2
3 and 4
1 and 4
2 and 3
