Form 5 Physics: Electromagnetism (Transformer Logic)

Question 🌷:

An ideal step-down transformer has a primary coil connected to an electrical supply, and its secondary coil is connected to a lightbulb, as shown in the diagram above. If the input power supply is switched from a 240 V alternating current AC source to a 240 V direct current DC source, what will happen to the lightbulb connected to the secondary circuit?
