Deals aimed at tempting iPhone users to upgrade their devices are starting to crop up. Walmart today is dropping the price of its iPhone 5s and iPhone 5c models to $99 and $29 from $149 and $49. Two-year activation is required for AT&T, Sprint or Verizon and each phone has 16 GB of memory.
A parallel circuit is an electrical circuit which has two or more paths for an electrical charge to flow through.The parallel circuit is the standard electrical circuit found in most homes and devices.Because it provides more than one way for a current to flow through to a device, it creates a much more stable and efficient power system than would otherwise be possible. The uses of the parallel circuit are manifold.arallel circuits are used inside many electrical devices and appliances. The main reason parallel circuitry is used in this context is to take advantage of more than one power source, like when more than one battery is being used in a portable device.
There are two ways that items are connected along a circuit: in series or in parallel. A parallel circuit connects devices along branched pathways, which provides separate paths for the electrons to flow. A series circuit connects devices in series, providing one single pathway for electron movement. We'll explore parallel circuits in detail in another lesson. For now, we'll focus on how series circuits work to power devices. A Single Pathway. Think of a series circuit like going through airport security. In order to get to your plane, you have to stop at a series of checkpoints and do so in a certain order.
