What happens if you add 2 light bulbs to a simple circuit?
A: There is no such a thing as simple circuit if the bulbs are put in series the light will dim if put in parallel both bulbs will light up the same provided the source can sustain the power increase
There are two light bulbs in a circuit wired in parallel a third light bulb is added again in parallel what is the effect on total resistance of adding the third bulb?
Total resistance decreases:1/R(total) = 1/R1 + 1/R2 + 1/R3Assuming each lightbulb has the same resistance: R1 = R2 = R31/R(total) = 1/R = 1/R + 1/R = 3/RR(total) = R/3Before the bulb was added:1/R(total) = 1/R + 1/R = 2/RR(total) = R/2R/3 < R/2
Client-based architecture advantages?
easily upgraded, added to the network with low costs, different hardwares and software work together on the same network (middleware)
What happens to the light bulbs in a series circuit?
The brightness of a lamp depends on its power rating, which is printed on the globe. This power rating onlyapplies at its rated voltage (e.g. 120 V in North America, and 230 V in Europe). When you connect lamps in series, you are connecting their individual resistances in series, and a voltage drop will appear across each lamp. For example, if you had, say, two 60-W lamps connected in series with each other across a 120-V supply, then 60 V would appear across each lamp, so the lamps would be considerably dimmer than their power ratings would suggest.The drop in power is not proportional to the drop in its rated voltage; it is considerably higher. It can be shown that for electric heaters, for example, a 10% drop in rated voltage causes a 19% drop in power! This is not necessarily the case for lamps, as their resistance changes significantly with temperature.If the lamps were of different power rating, then the lamps with the greater power rating would be dimmer than those with the lower power ratings -which is not what you might expect.
What were the colonial boycotts?
it is where the colonists go against a taxed product. Boycotts occurred in different years, about taxes on different products because the British continually added new taxes on different items. One colonial boycott was in 1765, when the British proposed taxes on many products. Another boycott was the Townsend Act in 1767. And another was The Boston Tea Party.
Is resistance in a series circuit equal to the largest resistor in the series?
No. The resistance in a series circuit is all the resistor values added together. eg. If two resistors were in a circuit, one was 10 ohms and the other was 30 ohms, the resistance in the circuit would be 30 ohms. Hope this helps!
If the resistance in the circuit is increased what will happen to the current and voltage?
* resistance increases voltage. Adding more resistance to a circuit will alter the circuit pathway(s) and that change will force a change in voltage, current or both. Adding resistance will affect circuit voltage and current differently depending on whether that resistance is added in series or parallel. (In the question asked, it was not specified.) For a series circuit with one or more resistors, adding resistance in series will reduce total current and will reduce the voltage drop across each existing resistor. (Less current through a resistor means less voltage drop across it.) Total voltage in the circuit will remain the same. (The rule being that the total applied voltage is said to be dropped or felt across the circuit as a whole.) And the sum of the voltage drops in a series circuit is equal to the applied voltage, of course. If resistance is added in parallel to a circuit with one existing circuit resistor, total current in the circuit will increase, and the voltage across the added resistor will be the same as it for the one existing resistor and will be equal to the applied voltage. (The rule being that if only one resistor is in a circuit, hooking another resistor in parallel will have no effect on the voltage drop across or current flow through that single original resistor.) Hooking another resistor across one resistor in a series circuit that has two or more existing resistors will result in an increase in total current in the circuit, an increase in the voltage drop across the other resistors in the circuit, and a decrease in the voltage drop across the resistor across which the newly added resistor has been connected. The newly added resistor will, of course, have the same voltage drop as the resistor across which it is connected.
In a series circuit each device that is added to the circuit decreases the what?
Depends on the device. If it is a resistor and you have a fixed voltage then the circuit will obey Ohms law. Voltage = Current x Resistance. So if R increases by adding more resistors in series and the voltage is constant, the current will decrease.
What is added to a circuit to make the current smaller?
The reduction of voltage or the increase of resistance will reduce the current in a circuit.
What would happen if another bulb was added to another series circuit?
In a series circuit, if another bulb is added, it is going to dim.
When you add resistors that are in a series to a ciruit?
You raise the total resistance by that amount if added in series to a circuit. If you add them in parallel to a circuit then that total resistance will be less than the total of the added circuit.
What happens when you add a resistor to a series circuit with a light bulb?
As you add more bulbs to a series circuit that means that the bulbs are in series to one another, therefore the total resistance is the sum of the individual resistance of the bulbs. If you add bulbs of the same resistance,then the rate at which the resistance changes will increase in a constant manner provided the current source is not altered. For instance if the bulb you are using is rated 20v,60w, then the current passing via the bulbs in series is the square of the voltage divided by the power in this case the current is approximately 7amperes.
If a new bulb is added and the electrical circuit becomes dimmer is it a parallel circuit?
No it's series circuit.
The low speed and second speed blowers doesn't work for the blower motor?
the reason blower does not work on all speeds, is the fan blower motor resistor. The resistor is a 4-5 step series circuit, 1 resistor is added for each reduction in speed. If one burns out then so will all speeds below it. The "high" circuit usually has a separate fuse and bypasses the resistor altogether.
When additional stops are added to a control circuit should they be connected in series or parallel?
series
If you have a DC passing through a circuit will the current decrease when you add a DC motor and if so by how much?
In the circuit where the DC motor is added, it was not specified whether the motor was added in series or in parallel to circuit elements. If it was added in series, it will increase circuit resistance and it will cause circuit current to go down. In parallel, the motor will reduce total circuit resistance, and circuit current will increase.
What would happen if more capacitors were added to a series circuit already containing two capacitors?
A: For one thing the total capacitance will decrease . If the voltage rating are different then more problem will become evident. That is if they are added in series.
