A coffee maker can be modeled as a heating element (resistance R) connected to the outlet voltage of 120 V (assumed to be dc). The heating element boils small amounts of water at a time as it brews the coffee. When bubbles of water vapor form, they carry liquid water up through the tubing. Because of this, the coffee maker boils 5.0% of the water that passes through it; the rest is heated to 100°Cbut remains liquid. Starting with water at 10°C, the coffee maker can brew 1.0 L of coffee in 8.0 min. Find the resistance R.
