Mechanical System Elements
engineering.nyu.edu• A pure damper dissipates all the energy supplied to it, i.e., converts the mechanical energy to thermal energy. • Various physical mechanisms, usually associated with some form of friction, can provide this dissipative action, e.g., – Coulomb (dry friction) damping – Material (solid) damping – Viscous damping
Chapter 7 Direct-Current Circuits
web.mit.eduthe potential energy is converted into thermal energy in the resistor. Assuming that the connecting wire carries no resistance, upon completing the loop, the net change in potential difference is zero, ε−IR=0 (7.2.3) which implies I R ε = (7.2.4) However, a real battery always carries an internal resistance r (Figure 7.2.3a),
