Greatest power rated resistor
Web10. A 50 Ω resistor, a 150 mH inductor and a capacitor C are connected in series to an AC emf source with V rms = 36 V and variable frequency. It is found that when the source frequency is set to 180 Hz 210 Hz 240 Hz the power delivered to the circuit is maximized. What is C? Answer: 5.21 µF 3.83 µF 2.93 µF WebThe heat dissipation within a resistor is simply the power dissipated across that resistor since power represents energy per time put into a system. So the relevant equation is the equation for power in a circuit: P = IV = I^2 …
