A plug-in transformer, like that in the fIgure below, supplies 6.00 V to a video game system. How many turns are in its secondary coil, if its input voltage is 115 V and the primary coil has 400 turns? Submit Answer Tries 0/99 What is its input current when its output is 1.30 A? Submit Answer Tries 0/99

A certain transformer has 120 V across the 100-turn primary coil and has 5 turns in the secondary coil. If the current in the primary coil is 0.1 A, how much power is dissipated in the secondary coil?

A transformer is designed for use in a neon sign. The input voltage is 120 V and the output needs to be 3000V. The output current is 50mA.  1. If 100 turns are placed on the primary coil, how many turns will need to be on the secondary coil? 2. What is the current in the primary set of coils? 3. What is the power output of the transformer?

Which of the following options correctly describes a transformer? A) a device that converts electrical energy into mechanical energy B) a device that converts mechanical energy into electrical energy C) a device that converts AC voltage to DC voltage D) a device that uses electromagnetic induction to transfer electrical energy from one circuit to another circuit.

A transformer has 90 turns on the primary coil and 175 turns on the secondary coil. If the AC input current is 5 A, the output current is Select one: O a. 2.6 A O b. 9.7 A O c. 3.5 A O d. 7.8 A

A cars bumper is designed to withstand a 4.0km/h (1.1 -m/s) collision with an immovable object without damaging the body of the car. The bumper cushions the shock by absorbing the force over a distance. Calculate the magnitude of the average force on a bumper that collapses 0.185m while bringing a 875kg car to rest from an initial speed of 0.85m/s in newtons.
