Energy Transfer Diagrams and Efficiency

Energy cannot be created nor destroyed. It can only be transformed from one form to another. Thus the 100J of electrical energy is transformed to 5 J of light energy and 95J of heat energy. In the case of the light bulb the 95J of energy transferred as heat is wasted energy as it is not useful because the purpose of the device is to produce light.

How to Select Bulbs and Fixtures | Lighting Patterns for Homes

For example, ten 100-watt bulbs operated for 1 hour would use 1 kWh of energy (10 bulbs x 100 watts x 1 hour = 1 kWh). Thus energy used for lighting can be saved either by reducing the power required for lighting or by reducing the time that the lighting is used. Efficacy. The efficacy of a bulb is the ratio of lumens produced to watts used.

How Electricity Flows

When you turn a light switch on, the electricity flows through a tiny wire in the bulb, which gets very hot and makes the gas in the bulb glow. When the bulb burns out, the tiny wire has broken - this means the path (circuit) is broken, so no electricity can flow. It''s the same with your TV - when you turn it on, you''re closing the circuit, so ...
