Maximum power dissipated
Web12 sep. 2024 · In addition, P a v e reaches a maximum when Z, which depends on the frequency, is a minimum, that is, when X L = X C and Z = R. Thus, at resonance, the average power output of the source in an RLC series circuit is a maximum. From Equation 15.5.18, this maximum is V r m s 2 / R. Webhave a power rating. This is the maximum power that can be dissipated from the The rate of conversion is the power of dissipation. Definition Power Dissipated in a resistor Using the formula for electrical power: . but and thus substituting in the equation for electrical power . This also works substituting ,
