Internal Resistance Formula, Explanation & Examples
WebResistance depends on an object’s size, shape, and material. In Figure 3 below, the cylinder's resistance is directly proportional to its length l l. The longer the cylinder, the higher the resistance. Figure 3. A uniform cylinder of length l l and cross sectional area A A. The longer the cylinder, the greater its resistance. WebWelcome to the Physics library! Physics the study of matter, motion, energy, and force. Here, you can browse videos, articles, and exercises by topic. We keep the library up-to-date, so … WebThe letter µ in physics: Linear density Linear density is the degree of mass per unit length. The value is especially useful for measuring the weight of objects that appear to be one-dimensional, such as threads, strings, yarn and wires. Linear density is represented mathematically as: µ = mass/length The SI unit of linear density is kg/m. bio clean mws
