Light bulbs. The filament in the bulb is heated in order for it to glow and produce light. This can be considered as a conversion of energy where heat energy is being transferred in light energy.
A magnifying glass is a device that uses light to produce an enlarged view of an object.
A device that uses a resistor to transform electrical energy into light and heat is an incandescent light bulb. The resistor, also known as a filament, has high resistance, which causes it to heat up and emit light as a result of the electrical current passing through it.
Both a toaster and a light bulb use electricity as a power source. They both have heating elements that produce heat when activated, although a toaster uses this heat to cook food while a light bulb uses it to produce light.
A fuel cell is a device that uses replenishable substances such as hydrogen or oxygen to produce electrical current through a chemical reaction. This process generates electricity and heat without combustion, making fuel cells a clean and efficient energy source.
A wind turbine is a device that uses the force of the wind to generate electricity. Wind turbines have blades that spin when the wind blows, turning a generator to produce electricity.

Light: lightbulbs, television sets, computer screens, indicator LEDs on different devices, a stove (the one that has an open flame). Heat: All of the above. Besides, just about any device that uses electricity will produce waste heat; for example a refrigerator, a computer, a radio, etc. Also, some devices are specifically designed to produce heat - such as the stove, a heater, or a hair drier.
