Question

Time (us) A uniform electric field collapses to zero from an initial strength of 6.0x105 N/C in a time of 15 us in the manner shown in the figure. Calculate the magnitude of the displacement current, through a 2.1 m2 area perpendicular to the field, during each of the time intervals "a", "b", and "c" shown on the graph. (Ignore the behavior at the ends of the intervals) What is the displacement current in the interval "a"? | 9.29×10-1 A You are or 161-2397 Your receipt no. is 161-2397 What is the displacement current in the interval "b"? 0.00 A You are correct. Your receipt no. is 161-1460 What is the displacement current in the interval "c"? 929 A Submit Answer Incorrect. Tries 7/100 Previous Tries

Explanation / Answer

(c)

Displacement current in the interval c,

i = e0*A*dE / dt

i = 8.85*10^(-12)*2.1*[(0 - 4*10^5) / (15*10^(-6) - 10*10^(-6))]

i = -1.486 A
