Question

CE Predict/Explain 24.29 Part A When a long copper wire of finite resistance is connected to an ac generator, as shown in the figure (a), (Figure 1 a certain amount of current flows through the wire. The wire is now wound into a coil of many loops and reconnected to the generator, as indicated in the figure Is the current supplied to the coil greater than, less than, or the same as the current supplied to the uncoiled wire? greater than less than the same as Submit My Answers Give Up Part B Choose the best explanation from among the following Less current is supplied to the circuit because the coiled wire acts as an inductor which increases the impedance of the circuit. More current flows in the circuit because the coiled wire is an inductor, and inductors tend to keep the current flowing in an ac circuit. O The current supplied to the circuit is the same because the wire is the same. Simply nothing Figure 1 of 1 wrapping the wire in a coil changes Submit My Answers Give Up rovide Feedba Continue

Explanation / Answer

part A) ---- ans is (b) less than

EXplanation

In the circuit (a) the resistance of the wire is R.In circuit (b) the resistance of the inductor is called as inductive reactance and it is due to the wounding of copper wire.

The inductor impedance is more than the resistance of the wire.so the current supplied to the coil is less than the current supplied to the single copper wire.

Part B)----- ans is Less current is supplied to the circuit because the coiled wire acts as an inductor, which increases the impedance of the circuit.

Explanation

As the circuit (b) consists of inductor the impedance of the circuit is incresed.so less current is supplied to the circuit.
