Question

A 1mF flat plate circular capacitor of radius 1 cm is charged to voltage V=1000 V. Its plates are then connected through a resistor R=1 Ohm. The magnetic field at its side (cylindrical) surface in the beginning of discharging equals:

	A.	0
	B.	2 T
	C.	20 mT
	D.	1.5 Wb
	E.	None of the above

Answer 1

soin using formula & Bode Godde م).لد वक on discharging at any time (t) charge capacitor (2) = cu ce-tirs) and d 오 doe at ca at Co e from cond s Bode - Moda at -AIRE e (B.?*%) = Mod (cue-tre) love thee Cuello at B = (220)R

at beginning of discharging ta B= Genevie) = (2x167) (1000) :) (10-2) (1) B=20X10-3 T 20m T
