Greatest power rated resistor
WebNov 20, 2024 · The power rating of a resistor is the maximum power the resistor can safely dissipate without too great a rise in temperature and hence damage to the resistor. (a) If the power rating of a 15-kO resistor is 5.0 W, what is the maximum allowable potential difference across the terminals of the 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
