An ideal step-down transformer has a primary coil of 370 turns and a secondary coil of 27 turns. Its primary coil is plugged into an outlet with 120 V(AC), from which it draws an rms current of 0.41 A. What is the voltage in the secondary coil? Submit Answer Tries 0/99 Calculate the rms current in the secondary coil. Submit Answer Tries 0/99 Assuming that the transformer secondary is driving a resistive load, calculate the average power dissipated in the resistor.

An ideal transformer is used to either increase or decrease the voltage in an AC circuit. When the voltage on the secondary coil is greater than that on the primary coil, then the number of turns on the secondary coil is __________ that on the primary coil. Group of answer choices larger than the same as smaller than

Problem 9: A neon sign requires 13 kV for its operation. A transformer is used to raise the voltage from the line voltage of 220 V (rms) AC to 13 kV (rms) AC. Part (a) Find the transformer s ratio of secondary to primary turns. Part (b) If the fuse in the transformer's primary winding blows at 0.65 A (rms), what is the maximum rms current, in milliamperes, that the neon sign can draw, assuming no power loss in the transformer? Δ Part (c) How much power, in watts, does the neon sign consume when it draws the maximum current the fuse allows?

The figure below shows an AC source, a transformer with a turns ratio of N₁/N₂ = 2.70, a source resistor Re, and a load resistor R₁. S' AVS R₂ ww ellee N₂ RL A voltmeter across the load resistor measures an rms voltage of 26.0 V when the load resistor R₁ is 48.0 and the rms source voltage is AV = 86.0 V. (a) Determine the value of the source resistor R (in ). How is the rms voltage across the secondary coil related to that of the primary? How is the power delivered to the primary related to the power delivered to the load resistor? How are the voltages across each element on the primary side related to each other? Q (b) What If? If the turns ratio is increased to 3.00, determine the source resistance (in 2) required to deliver the same amount of power to the load.
