When you touch the metal handle of the room -temperature stainless-steel frying pan, it feels cool to your touch. When you grab a room-temperature sauce pan by its plastic handle, A) it feels cooler than the metal handle because plastic conducts heat better than the metallic steel. B) it feels warmer than the metal handle because the steel handle conducts heat better than the plastic. C) it doesn't feel cooler or warmer than the steel. Why would it? Both handles are at room temperature! 2 points 2 points 2 points

Question 2 (2 points) Why is Ohm's Law relevant? Ohms law is extremely important to the world of electrical circuits and components but is not suitable for every electrical circuit and application. There are certain requirements that a circuit and electrical component should meet to ensure that Ohms law is applicable. Ohms law can be used to calculate the required value of Voltage or components within a circuit, it can also work out the amount of current that flows in an electrical circuit when resistors can be measured across electrical components such as voltage. Ohm's Law is not relevant Ohm's Law is only used in a DC circuit.
