Problem 28

Predict/Explain When a long copper wire of nite resistance is connected to an ac generator, as shown in Figure 2428(a), a certain amount of current ows through the wire. The wire isnow wound into a coil of many loops and reconnected to the generator, as indicated in Figure 2428(b). (a) Is the current supplied to the coil greater than, less than, or the same as the current supplied to the uncoiled wire? (b) Choose the best explanation from among the following: I. More current ows in the circuit because the coiled wire is an inductor, and inductors tend to keep the current owing in an ac circuit. II. The current supplied to the circuit is the same because the wire is the same. Simply wrapping the wire in a coil changes nothing. III. Less current is supplied to the circuit because the coiled wire acts as an inductor, which increases the impedance of the circuit.

(APPLAUSE) ... crossroads of a nation, land of Lincoln, let me express my deep gratitude for the privilege of addressing this convention. Tonight is a particular honor for me because, let's face it, my presence on this stage is pretty unlikely. My father was a foreign student, born and raised in a small village in Kenya. He grew up herding goats, went to school in a tin- roof shack. His father, my grandfather, was a cook, a domestic servant to the British. OBAMA: But my grandfather had larger dreams for his son. Through hard work and perseverance my father got a scholarship to study in a magical place, America, that's shown as a beacon of freedom and opportunity to so many who had come before him.
