A neon lamp requires a voltage of 8.0 kV (rms) to make the gas inside the lamp glow. In order to obtain such a high voltage, a step-up transformer is connected to an American outlet (120 Vrms, 60 Hz). If the secondary coil on the lamp's transformer has 3000 loops (or turns) of wire, how many loops (turns) does the primary coil have?
