#Battery n bulbs series#
There are two arrangements in which bulbs can be arranged in, either in series or in parallel. Factor #2: The arrangement of bulbs in an electric circuit Other than the presence of a power source or the number of batteries, let’s look at what are the other factors affecting the brightness of a light bulb. Note that too many batteries will overheat and make the bulb fuse instead. On the other hand, the more batteries an electrical system has, the brighter the bulb becomes because more batteries provide more electrical power to the circuit and the bulbs. to light up the bulb in the above electrical circuit). Without a power source, there would not be (electrical) energy for the system to do work (i.e. The bulb lights up when the electric current flows through the wire and the bulb and back to the power source. In this simple electrical system or circuit, it has wires which connect a bulb to a power source (e.g. It is represented in a circuit diagram with this symbol:įactor #1: Number of batteries/ power sourceĪn electrical system needs a power source to work. Understand that a light bulb is a circuit component that produces light using electricity. Must-Know Electricity Concept for Upper Primary/PSLE students: Factors affecting Bulb Brightness She decided to add in another bulb, bulb Y (shown in Figure 1) and her mother gave her another bulb, bulb Z, to form the electric circuit in Figure 2.Ī) What happens to the brightness of bulb X after adding bulb Y? Explain why?ī) What happens to the brightness of bulbs X and Y after adding bulb Z? Explain your answer.
Jess has an electric circuit with two batteries and one bulb, bulb X. Let’s shine a light on the captivating science behind bulb brightness This is the question on Bulb Brightness: Get ready to explore the captivating science behind every glow and discover the fascinating world of light bulbs. Together, let’s uncover the magic behind bulb brightness and ignite a spark of wonder in your child’s mind.
