Power rating of a resistor. The power rating of a resistor is the maximum power it can safely dissipate without being damaged by overheating. (a) If the power rating of a certain 15 $\mathrm{k} \Omega$ resistor is $5.0 \mathrm{W},$ what is the maximum current it can carry without damage? What is the greatest allowable potential difference across the terminals of this resistor? (b) If a 9.0 $\mathrm{k} \Omega$ resistor is to be connected across a 120 $\mathrm{V}$ potential difference, what power rating is required for that resistor?

$$1.61 \mathrm{W}$$

we're given a plant's off 15 killer home Resistance has a power rating off five. What? Now? We want to find out the maximum current that can pass through it. You know that power is ice. Where are which gives us? I square off. Eli. Where is the max? This is the maximum and off current that can flow through the appliance. If any more current flows, the power, we'll be over the power waiting on the medical report. And this maximum guarantees Sim, please. We're wrote off 505 in time. Stand by minus five. I'm sorry, my mystery. Because they're part of history because there is a killer on here. Excuse us. You don't want 0183 appear now for old age. We use the same formula people abused. He was a similar relation. It is us. The maximum possible all day is squared off. B R B times are just weird. Off five times. 15 times 10 part three. Excuse us. 175 words five by five b. You want to find out the minimum rating required for a 9.0 kilo home? Our plans to run on 1 40 world. For this, the cooperating would have to be. We swear by our which is 120 square, divided by the resistance, which is nine times thank you, which turns out to be 1.61 If the power rating off the appliance is 1.6. What are more, the appliance run smoothly at this voltage. For this given assistance, if the tolerating is lesser, the medical is going too far.
