32. A neon sign transformer has 450 W AC output with an rms voltage of 15 KV when connected to normal household outlet (120 V). There are 500 turns of wire in the primary coil. (a) How many turns of wire does the secondary coil have? (b) When the transformer is running at full power, what are the currents in the secondary coil and in the primary coil? (c) What is the peak current in the primary coil?
The output rms voltage of a 480 W transformer is 240 V and the input rms current is 0.4 A. The primary coil has 200 turns, how many turns does the secondary could have?
You have a low voltage lighting system that requires a 24 V RMS source, but all that is available is the 120 V RMS outlet on the wall (frequency of 60 Hz). If you make a transformer with the primary coils hooked up to the source voltage and the secondary coils hooked up to the lighting system, how many coils would you design the primary and secondary coils of the transformer to have? How would the power dissipated...
5. (10 pts) A transformer is designed to have an output voltage of 1350 V (rms) when the primary coil is connected to a 150V (rms) source. (i) Is this a step-up or step-down transformer? f there are 2700 turns on the secondary winding (coil), how many turns are required on the primary? (ii) If a load resistor across the secondary draws a peak current of 1.5.A, what is the peak and the rms current in the primary?
A neon sign transformer has a 420W AC output with an rms voltage of 13 kV when connected to a normal household outlet. There are 500 turns of wire in the primary coil. Part A How many turns of wire does the secondary coil have? ( it is not 48750, 45500n 49636, or 5.0x10^4) Part B How many turns of wire does the secondary coil have? Part C The current in the primary coil?
The outlet voltage inside a house is 120V, but the voltage at the power line that supplies the neighborhood is much higher. A transformer between the power line and the house has 5000 turns in the primary coil and 500 turns in the secondary coil. What is the voltage of the power line supplying electricity to the neighborhood?
The primary 40-turn coil of an ideal transformer is supplied with 120 V (rms). If the rms voltage output of the secondary coil is 15 V, how many turns are in the secondary coil, and what type of transformer is this? 8 turns, step-down transformer 5 turns, step-down transformer 15 turns, step-down transformer 320 turns, step-up transformer 160 turns, step-up transformer
An engineer designed a transformer to convert 120 V (rms) to 6.0 V (rms). The number of turns in the primary is 540, and the secondary current is 610 mA at an output voltage of 6.0 V (rms). How many turns are in the secondary? Group of answer choices 5 27 90 3 240
electromagnetic 17) Transformers: (5 pts) The voltage across a local transmission line is about 12,000 V. Assuming that the primary coil on a transmission line transformer has 10,000 turns, how many turns does the secondary coil need to have in order to step-down the transmission line voltage to the usable household voltage of 120 V?
