Dependable voltage; and you don't need to have all devices on or off simultaneously.
Home devices are connected in parallel and not in series.
A parallel circuit
A parallel circuit is different in many ways from a series circuit: 1. In parallel, the voltage across all the devices connected is the same. 2. If a fault occurs in any device connected in parallel combo, then it has no effect on the operation of the other device. 3. In series circuit the current flowing through all the devices is the same while in case of the parallel one the voltage across all the devices is same.
A power bar is a type of parallel circuit where multiple outlets are connected to a common power source. This allows multiple electronic devices to be connected and powered simultaneously.
Parallel for main circuits and series parallel for lighting circuits.
Separate devices should always be hooked up in parallel, and not series. Therefore, you would combine the total current requirement, which in this case is 600mA or 0.6A. You would therefore need a 9V power supply that is capable supplying at least 0.6A. It depends on whether the devices are connected in series or parallel or some combination of the two. The current in a series circuit is the same throughout the circuit. The current in a parallel circuit is the sum of the current in each parallel branch If the three devices are connected in series, the required current is 200mA. If the three devices are connected in parallel, the required current is 600mA The total power required by a circuit is the sum of the power consumed by each component. It doesn't matter if the devices are connected in series or parallel. Power = voltage x current. If the three devices are in series, the power consumed by one of them is 9 x .2 = 1.8 watts. The total power consumed is 1.8 x 3 = 5.4W If the three devices are connected in parallel, the power consumed is 9 x .6 = 5.4W Notice that the power consumed is the same for the series and parallel combination. The battery (or power supply) must be able to supply 5.4 watts.
Depending on the device to be powered, a.c. current may be used directly, or converted to d.c. Electric lighting, motors, and heating appliances, typicaly use a.c. power directly. Electronic appliances that have bipolar, semiconductor devices, convert a.c. current to d.c. due to the fact that these devices must be connected (biased) in a particular polarity. These devices would be destroyed if connected to a.c.
It was mentioned that there are two different ways to connect two or more electrical devices together in a circuit. They can be connected by means of series connections or by means of parallel connections. When all the devices in a circuit are connected by series connections, then the circuit is referred to as a series circuit. When all the devices in a circuit are connected by parallel connections, then the circuit is referred to as a parallel circuit. A third type of circuit involves the dual use of series and parallel connections in a circuit; such circuits are referred to as compound circuits or combination circuits. The circuit depicted at the right is an example of the use of both series and parallel connections within the same circuit. In this case, light bulbs A and B are connected by parallel connections and light bulbs C and D are connected by series connections. This is an example of a combination circuitBy EngineerMuhammad Zaheer Meer GMS
In a parallel circuit the voltage across each component is the same.
Electrical devices are devices that operate through electricity, while electrical appliances are specific types of devices that are designed to perform a particular household function, like refrigerators, TVs, or microwaves. Essentially, all electrical appliances are electrical devices, but not all electrical devices are necessarily classified as appliances.
The purpose of a receptacle in an electrical circuit is to provide a point where electrical devices can be connected to receive power. It serves as an outlet for plugging in devices such as lamps, appliances, and electronics to access electricity for operation.
A shunt is connected in parallel with an ammeter. Any current applied to parallel devices will divide betwen them, so the ammeter will pass only a part of the total current.
