To find the resistance of the toaster, you can use Ohm's law, which states that resistance (R) is equal to voltage (V) divided by current (I):
Resistance (R) = Voltage (V) / Current (I)
In this case, you have the power (P) and voltage (V) of the toaster. Power (P) is given in watts (W), and voltage (V) is given in volts (V).
Power (P) = Voltage (V) * Current (I)
We know the power (P) is 100W, and the voltage (V) is 220V. Now we can rearrange the formula to solve for the current (I):
Current (I) = Power (P) / Voltage (V)
Current (I) = 100W / 220V
Now, let's calculate the current:
I ≈ 0.4545 Amperes (A)
Finally, to find the resistance (R), use Ohm's law:
Resistance (R) = Voltage (V) / Current (I)
Resistance (R) = 220V / 0.4545A
Resistance (R) ≈ 484.848 ohms (Ω)
So, the resistance of the toaster is approximately 484.848 ohms.
