Yes, the placement of the switch does matter in a series circuit. Placing it before a component will interrupt the flow of current to the entire circuit, while placing it after a component will only interrupt the current to that specific component.
I'm not sure what you mean by turning a dimmer switch "up".-- When the dimming action of the device is turned 'up', the bulbbecomes more dim, that is, less bright.-- The dimmer may have an arrow printed on its control, labeled 'brighter'.In that case, when you turn the control in the direction of the arrow,the light becomes brighter, i.e. less dim.
Yes, both a key switch and a reed switch have standard symbols that can be used in circuit diagrams. The symbol for a key switch is typically represented as a rectangle with a gap in the top portion, symbolizing the key inserted. The symbol for a reed switch is often depicted as a rectangle with two parallel lines inside to represent the reed contacts.
You can create a simple circuit switch out of a paper clip, two nails, and a battery. Use the paper clip as a bridge to connect the two nails and complete the circuit. When the paper clip touches both nails, the circuit is closed, allowing the electricity to flow.
A series circuit has more than one resistor and gets its name from only having one path for the charges to move along. Charges must move in "series" first going to one resistor then the next. If one of the items in the circuit is broken then no charge will move through the circuit because there is only one path. There is no alternative route. Old style electric holiday lights were often wired in series. If one bulb burned out, the whole string of lights went off.
A voltmeter is designed to operate like a very large resistor (order of megaOhms), in parallel to the circuit that it is measuring. As long as the voltmeter resistance is much larger than the circuit that it is measuring, it will draw very little current away from the circuit and will only minimally disturb the operating circuit. See related link. If the voltmeter is connected in series with the rest of the circuit, then that is the same as connecting a very large resistor in series.So for example if you have 10 volt battery and a 10 ohm resistor, that would be 1 amp (without the voltmeter). Now if the voltmeter is 10 megaohm, the total resistance is 10000010 ohms, so the current is 0.999999 microamperes, and the voltage across the 10 ohm resistor is 9.99999 microvolts, while the voltage across the voltmeter is 9.999990 Volts (these numbers are rounded, but you get the idea).Suppose you put in series with a 1 kiloOhm (not sure about that spelling) resistor. The total resistance is 10001000 ohms, and current is 0.99990 microamperes, the voltage across resistor is now 0.9999 millivolts (it was microvolts) and the voltage across the voltmeter is 9.9990001 volts
From the standpoint of basic functionality, you can put the switch anywhere. In a series circuit, there is only one path for current flow. If you open the switch, you interrupt that pathway and turn the circuit "off."There may be practical reasons to put the switch in one place or another, however. Sometimes it's put in a particular place in the circuit for manufacturing reasons. In other circuits, safety may dictate that you put the switch in a particular place: in a ground-referenced circuit for example, you may want to put the switch so that one side is at the ground point.
Switches used in electrical circuits are wired in series with either a parallel or series load. In parallel loads, the switch is upstream from the parallel circuit, so that the switch will shut off all of the parallel circuits.
A switch.
Since (by Kirchoff's current law) the current in a series circuit is the same at every point in the series circuit, it does not matter where you place the ammeter.
When checking continuity in a series circuit, you put your leads in series with the circuit or device being checked. You also make sure the circuit is deenergized and that it is open.
in a series circuit or it will not work. Put it after the bulb
switching on the tourch for example is when as you switch it on it will move the switch connecting it to a circuit that lights up the bulb and when you switch the switch off the switch will move breaking the circuit
-- If all the bulbs are in series, then the switch can be at any pointin the series ring, and it will control them all.-- If any bulbs are in parallel, then in order to control all of them, theswitch must be between the circuit and one terminal of the battery orpower supply.
It does not matter what line in (the phase or neutral) is the fuse. In a closed series circuit current in all areas of the circuit is equal. It's best to put the fuses in both wires (phase and neutral) and even better for each individual device in the chain.
The switch will not increase the current. The only thing that will increase the current is adding a larger load.Another AnswerTo maximize current flow in a circuit with 2 Flashlightbatteries, 2 Flashlight bulbs, and a switch, set aside the bulbs, put the batteries in series, connect the switch between the end poles of the battery set, and close the switch. The batteries will get hot and probably leak electrolyte, and be drained in seconds.If you want to maximize current through the circuit withthe bulbs in it, connect the bulbs in parallel to each other, and in series with the switch.
because rubber is an insulator
A switch in a circuit will quickly allow you to break the circuit, without changing the wiring. For example, a light switch. By turning a light switch off, you are breaking the circuit and, thus, turning the light off.
