The 380-turn primary coil of a step-down transformer is connected to an ac line that is 120 V (rms). The secondary coil voltage is 6.50 V (rms). 1)Calculate the number of turns in the secondary coil. (Express your answer to two significant figures.)

A neon sign transformer has a 430 W AC output with an rms voltage of 13 kV when connected to a normal 120 V household outlet. There are 200 turns of wire in the primary coil. Part A Assume the transformer is running at full output: in this case, what is the current running through the secondary coil? Express your answer as the number of the turns. Π| ΑΣΦ I₂ = Submit Request Answer A

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

A neon sign achieves high voltage with a transformer with 300 primary coil turns.  The rms voltage is 120 V at primary, and 10 kV at secondary.  The secondary coil has _____ turns.
