The diagrams show three circuits with identical batteries, identical inductors, and identical resistors. Rank them according to the current through the battery just after the switch is closed, from least to greatest. 3,2,1 2 and 3 tie, then 1 1,3,2 1, 2, 3 3,1, 2 Lines of the magnetic field produced by a long straight wire carrying a current. are in the direction of the current. are opposite to the direction of the current. leave the wire radially are circles concentric with the wire. are lines similar to those produced by a bar magnet. Note the following circuit elements: (1) resistors. (2) capacitors, and (3) inductors. Which of these elements has NO power output, on the average, in an AC circuit? (1) only (2) only.(3) only both (1) and (3) both (2) and (3) An electric field exists in the cylindrical region shown and is parallel to the cylinder axis. The magnitude of the field might vary with time according to any of the four graphs shown Rank the four variations according to the magnitudes of the magnetic field induced at the edge of the region, least to greatest. 2,4,3,1 3 and 4 tie, then 1, 2 4.3,2,l 4,3,1, 2 (E) 2,1,3,4 Which statement is true concerning the impedance of an RLC circuit? It is independent of frequency It depends only on the resistance. It depends only on the values of C and L It is dominated by the resistance at high frequencies It is dominated by the capacitance at low frequencies A battery is used to drive a circuit, but after a certain amount of time, the current is zero. When the same circuit is driven by a sine wave generator the current is non-zero and alternates. Which combination of elements is most likely to comprise the circuit? resistors only inductors only C. capacitors only a combination of inductors and resistors a combination of capacitors and resistors
