part 2 "The armature of a 60 Hz ac generator rotates in a 0.34 T B-field. The area of the coils is 0.07 m2."
The primary coil of a transformer has 1,419 loops. The secondary coil has 292,232 loops. The primary coil has a 62 A current and 87 V. A.) Is this a step-up or step-down transformer? How do you know? Choose one of the following. It is a step-down transformer because the secondary has more loops than the primary. OO 000 It is a step-up transformer because all transformers are step-up transformers. It is a step-down transformer because the primary current is less than the primary voltage It is a step-up transformer because the secondary has more loops than the primary. It is a step-up transformer because the primary current is less than the primary voltage It is a step-down transformer because all transformers are step-down transformers B.) Determine the power of the primary coil. C.) Assuming no losses, determine the power of the secondary coil. D.) Calculate the voltage in the secondary coil. E.) Calculate the current in the secondary coil. Part 2: Generators The armature of a 60 Hz ac generator rotates in a 0.34 T B-field. The area of the coils is 0.07 m². A.) Determine how many loops must be wound around the armature if the peak output is to be 200 V. N= loops B.) Determine what the current & power output (not the power loss) will be if the resistance of the coil is 0.2 0. 1= P=
