A 22 volt source is connected to a 4.4 Ω resistor with a cylindrical shape of...
Two parallel conductor rails with negligible resistance are
connected at one end by a resistance resistor R=1.40 Ω, as shown in
the figure. The rails are placed in an upwardly directed magnetic
field B= 5.00 T , which is perpendicular to the plane of the rails.
This magnetic field is uniform and independent of time. The
distance between the rails is l= 0.20 m. A conductor bar slides
without friction on the top of the two rails at a constant...
What voltage will produce 0.35 A of current through a 4800-Ω resistor? A 9.0-V battery is connected to a bulb whose resistance is 2.2 Ω How many electrons leave the battery per minute? What is the resistance of a 7.4-m length of copper wire 1.4 mm in diameter? The resistivity of copper is 1.68×10−8Ω⋅m A 12-V battery causes a current of 0.72 A through a resistor. What is its resistance? How many joules of energy does the battery lose in...
