What is the total voltage drop across a set of resistors in series?
Simply add all of the component's resistances together and that will give you circuits total resistance. If you're dealing with a 'series-parallel', or 'parallel' circuit, the equations will change, but in a simple series circuit, the total resistance is just the total of all the component's resistance.
What do parallel circuit NOT have in common with series 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.
Why the relative brightness of two light bulbs change when the type of circuit is changed?
When your circuit is in SERIES, each individual bulb will receive one fraction of the voltage of the battery, allowing the full chain of bulbs to draw less current, but to be dimmer in the same respect. When your circuit is in PARALLEL, each bulb will receive the same voltage, however more current will be drawn, so it depends on your situation on which you should use.
What happens to the current if the number of bulbs stays the same but you use more cells?
If you add more cells in series with the bulbs, the current will increase as the voltage across the bulbs increases. If you add more cells in parallel with the bulbs, the current will stay the same because the voltage of the cells does not increase when they are added in parallel.
In a series circuit what happens to the current if you increase the number of components in the circuit?
The current (amps) will remain constant, but the voltage will drop.
Do relays use high voltage to control low currant circuits?
Low voltage to operate relay controlling high CURRENT circuits (currant is a dried fruit).
When would you use a series and when would you use a parallel circuit?
* The most common applications for series circuits is in Christmas tree lights and putting a fuse in series with delicate electronic equipment. * Each component in a circuit causes a voltage drop. Therefore, the series circuit should only be used where the voltage drop does not interfere with the proper functioning of the components in the circuit. * On the other hand, where all of the compenents in a circuit require the same supply voltage, then a parelell circuit should be used.
How are parallel circuits and series circuits alike?
in parallel the voltage stays the same in parallell the current is shared in series the voltage is shared in series the current stays the same the main similarity between parallel and series circuits is when voltage increases, current increases.
What is a solution of series circuits?
All the volt drops across each component in the series circuit will add up to the emf of the battery or power supply. Note the voltage supplying the circuit and divide it by the sum of all the resistances in the circuit. This gives you the current which is the same through all components. Take a component's resistance and multiply by the current and you have the voltage drop across it.
What is the potential difference and current characteristics in a series and parallel circuit?
In a simple parallel circuit -- for example, two resistors in parallel with a voltage source -- the voltage across the terminals of each component is the same. The current, however, 'splits' in order to take the two separate paths. In this case, you would use Ohm's law to find the current through each branch. In other words:I1=V/R1, I2=V/R2.If you have a current source instead of a voltage source, you would use current division to calculate current:I1=Isource*R2/(R1+R2), and I2=Isource*R1/(R1+R2).This is all in contrast with a simple series circuit, in which the current is the same through each component but the voltage drops are different. In which case you would use Ohm's law or Voltage division to calculate the individual voltages, depending on the source.
When would you use current transformer?
A 'current transformer' (CT) is classified as an instrument transformer, which means it is used to provide a small secondary current that is in proportion to its large primary current, for purposes of metering or protection. At the same time, it electrically-isolates the secondary (metering) circuits from the primary circuits (which are often high-voltage circuits) for the purpose of safety.
Explain the rheostat and its advantages in electric circuits?
Advantages in electric circuits : Advantages of using the rheostat in electric circuits is optional as you could just use the dial on the power-supply to vary the voltage (p.d.), and therefore the current. The advantage of using the rheostat is that you can control it to give you nice even numbers for the voltage.
What is the total voltage drop across a set of resistors in series?
Simply add all of the component's resistances together and that will give you circuits total resistance. If you're dealing with a 'series-parallel', or 'parallel' circuit, the equations will change, but in a simple series circuit, the total resistance is just the total of all the component's resistance.
How do parallel circuits use current and voltage?
Kirchoff's voltage law: In a series circuit, the signed sum of the voltage drops around the circuit add up to zero. Since a parallel circuit (just the two components of the parallel circuit) also represents a series circuit, this means that the voltage across two elements in parallel must be the same.Kirchoff's current law: The signed sum of the currents entering a node is zero. In a series circuit, this means that the current at every point in that circuit is equal. In a parallel circuit, the currents entering that portion of the circuit divide, but the sum of those divided currents is equal to the current supplying them.
What is the use of series and parallel resonance?
Series resonant circuits have their lowest impedance at the resonant frequency. Parallel resonant circuits have their highest impedance at the resonant frequency. This characteristic is exploited in the design of filters, oscillators and other circuits.
What is the equivalent resistance through the enire circuit of 90 volts?
Not enough information. In the case of simple circuits, usually you would add resistances that are in series, and use a slightly more complicated formula for resistance that are in parallel. You CANNOT determine an equivalent resistance known only the voltage. However, if you know the total current, you can divide the voltage by the total current to get the equivalent resistance.
