WebJun 27, 2024 · Two identical heaters of 240v, 1000W are connected in series across a 240 volts line; To find: Combined power; P=v²/r. 1000=220²/r. 1000r=48, 400. r = 48.4 ohms. Given two such heaters are connected in series. So, Req = 48.4×2. Req = 96.8 ohms. Now we have to find power: P=220²/96.8. P=500 Watts. The combined power of the heaters will be ... WebSep 3, 2024 · as two heaters are identical both will consme eqal power at equal potential drop . as there resistances are equal so 220 volt each will drop on each heater . now at 220V heater consume 1000W power . so ech will consme 1000W power . total power consumed =2*1000=2000W
WebAug 31, 2024 · Let resistance of each heater be ROmega Given that the power of each heater is 1000W when connecred across 240V. So 1000=240^2/R =>R=240^2/1000Omega … WebQuestion. 18.
