How to Calculate the Resistance of a Toaster Connected to a Household Outlet

What is the resistance (in ohms) of the toaster?

Given the wattage and voltage, how can we determine the resistance of the toaster?

Final answer:

Given the wattage and voltage, the resistance of the toaster can be calculated using Ohm's law. The current (I) is calculated by dividing the power (583 Watts) by the voltage (120 Volts), resulting in approximately 4.86 Amperes. The resistance (R) is then found by dividing the voltage by the current, approximately 24.69 Ohms.

Explanation: The 583-Watt toaster connected to a 120-Volt household outlet involves a Physics problem related to Ohm's law. Ohm's law states that the resistance of a circuit is equal to the voltage divided by the current (I=V/R). Here, the power (P) is given by the product of the voltage (V) and the current (I). So to find the resistance (R), we first need to find the current using the power and voltage (I=P/V). We then use Ohm's law to find R=V/I. First, we calculate the current: I=583 Watts / 120 Volts = 4.86 Amperes. Then, using this current, we calculate the resistance: R = 120 Volts / 4.86 Amperes = 24.69 Ohms. Thus, the resistance of the toaster is approximately 24.69 Ohms.
