Homework Statement
A toaster with 18Ω is conducted to a 220 volt source. What is the power consumed by the toaster.
Homework Equations
P=IV
The Attempt at a Solution
P=18(220)
P= 3,960
You have multiplied the resistance by the voltage, the formula you stated was for current by voltage.tDexx said:Homework Statement

Power consumption refers to the amount of energy consumed by a device or system to perform its intended function. It is typically measured in watts (W) or kilowatt-hours (kWh).
Power consumption is important because it directly impacts the cost of operating a device or system. It also has implications for the environment, as the generation of electricity often involves the burning of fossil fuels.
Several factors can affect power consumption, including the efficiency of the device, the workload it is performing, and the duration of its use. Other factors such as temperature, voltage, and current can also play a role.
There are several ways to reduce power consumption, such as using energy-efficient devices, optimizing workload distribution, and implementing power-saving features. Other strategies include using renewable energy sources and improving insulation and ventilation in buildings.
Power consumption is typically measured using a wattmeter, which calculates the amount of energy used over a specific period of time. It can also be estimated by measuring voltage and current and using Ohm's law (P=VI) to calculate power.
