Question

You are stranded on a raft. Luckily, a 200 m of 14-gauge insulated copper wire, a light bulb rated at 5.0 V battery, a large piece of iron, plus other tools such as wire cutters float by. You manage to grab these items. You cannot make a fire because you risk destroying your raft. Fortunately, a helicopter always flies over you at night. You should probably try to get the helicopter's attention if you want to be saved. How do you do it with the tools you have?! You could make a circuit to light the light bulb! What is the current of the circuit? What is the resistance of the circuit? (Do not use R = (pL)/A)
