Square-Wave Voltage II The square-wave voltage shown in Figure 2427 is applied to an RC circuit. Sketch the shape of the instantaneous voltage across the capacitor, assuming the time constant of the circuit is equal to the period of the applied voltage.
Chapter 18: Law of Thermodynamics Zeroth Law of thermodynamics: If object A is in thermal equilibrium with object B, and object B is separately in thermal equilibrium with object C, then objects A and C will be in thermal equilibrium if they are placed in thermal contact The first law of thermodynamics is a statement of the conservation of energy. o If a system’s volume is constant, and heat is added, its internal energy increases. o If a system does work on the external world, and no heat is added, its internal energy decreases Work done by an expanding gas, constant pressure: W = PV o If the volume stays constant, nothing moves and no work is done. o If the temperature is constant, the pressure varies inversely with the v
