Unformatted text preview: In the circuit shown to the left CI = 1.0
C2= 2.9uF, and C3= 4.0}1F.A voltage of
28.0 V is applied across pomts a and b.
After C I is fully charged the switch is
thrown to the right. What is the ﬁnal charge and voltage on each capacitor? A conducting rod AB moves to the right
without friction with a velocity of 6.0 m/s
in contact with conducting rods connected
to a resistor R=2.0 ohms as shown. The
entire apparatus is in a uniform magnetic
ﬁeld of 0.40 Tesla out of the page and
perpendicular to the plane of the page. 3.. Find the emf induced in the rod AB. b. Find the magnitude and direction of the current in the rod AB.
Assume R is the total resistance in the circuit. Find the force necessary to maintain the constant velocity v.
Find the power used to maintain v and compare it to the power
loss in the resistor. 9.0 6. a. Use Ampere’s Law to determine the magnetic
ﬁeld B in the toroidal solenoid shown to the right. The
air core toroid carries a current i , has a radius r, total
turns N and cross section area A as shown. b. Use your result from part a to obtain the self
inductance L of the toroid. Assume the magnetic ﬁeld
is uniform over the area A. ...
