If two or more components are connected in parallel they have the same potential difference voltage across their ends. The potential differences across the components are the same in magnitude, and they also have identical polarities.
The same voltage is applicable to all circuit components connected in parallel. Consider a very simple circuit consisting of four light bulbs and one 6 V battery. If a wire joins the battery to one bulb, to a second bulb, to a third bulb, then back to the battery, in one continuous loop, the bulbs are said to be in series.
If the three light bulbs are connected in series, the same current flows through all of them, and the voltage drop is 1. If the light bulbs are connected in parallel, the current flowing through the light bulbs combine to form the current flowing in the battery, while the voltage drop is 6. When one light bulb is removed from the series circuit, the other two light bulbs go out.
When a bulb is removed from one branch of a parallel circuit the following occurs: The voltage remains the same. The total current decreases. Parallel circuits the rule is: The voltage stays the same and the current divides in each branch. The other bulbs will stay lit. Each bulb sees the full voltage when the bulbs are in parallel. When a bulb gets more power, it will glow brighter.
The effective resistance of the circuit is reduced by the parallel combination of resistors. It glows brighter. Increasing the number of bulbs decreases the brightness of the bulbs. What changes occur in the resistance in the circuit as more bulbs are added? The resistance increases. In a series circuit, adding bulbs increases the resistance in the circuit.
If the light bulbs are connected in parallel to the voltage source, the brightness of each bulbs less or more constant. If more light bulbs are added in the parallel combination then the current increases as the net resistance decreases. The brightness of the light bulbs increases. When you plug in that second bulb, both will get equally dim, because you have added more resistance to your circuit, which decreases the flow of current. Adding another light bulb in series decreases the current because our battery now has more work to do!
You just add all of the different resistance values together. Parallel circuits are harder to construct and cost more money, but the advantage is that when one part of the circuit goes out, the device will keep working. For example, in a house or apartment, if one light goes out, the rest of the lights will stay on.
Series circuits , by contrast, arrange all of their elements in a single, closed loop. When appliances are connected in a parallel arrangement, each of them can be put on and off independently. Also, if the appliances were wired in series , the potential difference across each appliance would vary depending on the resistance of the appliance.
Unlike LEDs that are wired in series, LEDs wired in parallel use one wire to connect all the positive electrodes of the LEDs your using to the positive wire of the power supply and use another wire to connect all the negative electrodes of the LEDs your using to the negative wire of the power supply. In short, wiring in series divides the total power supply between the LEDs.
Wiring them in parallel means that each LED will receive the total voltage that the power supply is outputting. But if the LED lens is significantly cracked or damaged, then anywhere from half to the full set will go out.
For one, the total resistance of a Parallel Circuit is NOT equal to the sum of the resistors like in a series circuit. An example of a parallel circuit is the wiring system of a house. A single electric power source supplies all the lights and appliances with the same voltage. If one of the lights burns out, current can still flow through the rest of the lights and appliances. The first circuits were very simple DC circuits.
Parallel circuits are used in homes because the loads can be operated independently of each other. If the circuit contained only lights, the lights would get dimmer with the addition of more lights. Each load gets the full voltage of the circuit. Rope light spools can be cut using either sharp scissors or a knife. To cut rope light, measure the area where you plan to install the rope light and then cut the tube at the nearest cutting mark.
