- A generator connected to the wheel or hub of a bicycle can be used to power lights or small electronic devices. A typical bicycle generator supplies 6.00 V when the wheels rotate at = 20.0 rad/s. (a) If the generator's magnetic field has magnitude B = 0.600 T with N = 100 turns, find the loop area A. (b) Find the time interval between the maximum emf of +6.00 V and the minimum emf of 6.00 V.arrow_forwardShow that Equation 32.28 in the text Ls Kirchhoffs loop rule as applied to the circuit in Figure P32.56 with the switch thrown to position b.arrow_forwardA rectangular conducting loop is placed near a long wire carrying a current I as shown in Figure OQ23.5. If I decreases in time, what can be said of the current induced in the loop? (a) The direction of the current depends on the size of the loop. (b) The current is clockwise. (c) The current is counterclockwise. (d) The current is zero. (e) Nothing can be said about the current in the loop without more information.arrow_forward
- A circuit consists of a conducting movable bar and a light bulb connected to two conducting rails as shown in Figure OQ23.16. An external magnetic field is directed perpendicular to the plane of the circuit. Which of the following actions will make the bulb light up? More than one statement may be correct. (a) The bar is moved to the left. (b) The bar is moved to the right. (c) The magnitude of the magnetic field is increased. (d) The magnitude of the magnetic field is decreased. (e) The bar is lifted off the rails.arrow_forwardA 140-mH inductor and a 5.50-0 resistor are connected with a switch to a 6.00-V battery as shown in the figure below. (a) After the switch is first thrown to a (connecting the battery), what time interval elapses before the current reaches 220 mA? ms (b) What is the current in the inductor 10.0 s after the switch is closed? A (c) Now the switch is quickly thrown from a to b. What time interval elapses before the current in the inductor falls to 160 mA? msarrow_forwardJohn is using a cordless electric weed trimmer with a dc motor to cut the long weeds in his backyard. During normal operation the trimmer generates a back emf of 16 V when it is connected to an emf of 24 V dc. The total electrical resistance of the motor is 8.0 Ω. (a) How much current flows through the motor when it is running smoothly? (b) Suddenly the string of the trimmer gets wrapped around a pole in the ground and the motor quits spinning. What is the current through the motor now? (c) How does the amount of heat dissipated in the motor during normal operation compare to the amount of heat dissipated when the motor is stuck? Calculate the ratio of the two amounts.arrow_forward
