Consider a simple transformer that has a 100-turn primary coil and a 1000-turn secndary coil. The primary is connected to a 120-V AC source and the secondary scoil is connected to a light bulb with 1000 ohms of resistance. What is the current through the bulb? What is the power in the bulb? What is the power in the primary coil? What is the current in the primary coil?
