A step-up transformer is used to power a neon sign. The sign has a resistance R=10ka. The current in the secondary coil is 5mA. The transformer takes 120 V input voltage. How much power is delivered by the source to the neon sign? Select one: O a. 1.44 W o b. We need to know the number of turns in primary and secondary. Oc.0.25 W
