Correct option is D
Correct answer is (D) 44Ω
Solution : To find the resistance of the toaster coil, we can use the formula derived from Ohm's Law and the power formula:
P is the power (1100 W)
V is the voltage (220 V)
R is the resistance (which we need to find)
Rearranging the formula to solve for R:
Substituting the values:
So, the resistance of the coil is 44Ω.
Information Booster:
- The power of an electrical device, like a toaster, is related to its voltage and resistance by the formula . This shows that the power is inversely proportional to the resistance when the voltage is fixed.
- If the resistance were higher, the power consumption would decrease for the same voltage. Conversely, a lower resistance would increase power consumption.
- Resistance (R) is a property of the conductor (in this case, the toaster's coil), and it depends on factors like material, length, and cross-sectional area.
