What's More Activity 2: Qualitative Problems Direction: Answer the following questions. (1) Good thermal conductors are said to be good electrical conductors. If so, why is it that cords used to connect toasters, irons, and heat-producing appliances get hot by the conduction of heat from the heating element? (2) How would you expect the resistivity of a good insulator such as glass or polystyrene to vary with temperature? (3) A fuse is a device that is designed to break the circuit. It melts when the current exceeds its value. What characteristics should the material have?

Ohm's law

Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.

Path of Least Resistance

In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
