What is the relationship between voltages in a series circuit?
The rule for voltage in a series circuit is that the signed sum of the voltage drops around the circuit add up to zero. This is Kirchoff's voltage law. Take a simple circuit of a 1.5V battery and light bulb in series with each other. Starting at the battery negative terminal, the voltage from negative to positive is +1.5V. Starting at the top of the light bulb (the end connected to the battery positive terminal), the voltage from top to bottom is -1.5V. The two drops (rises, in this case), +1.5V and -1.5V add up to zero. Note that the simple example above, is also a parallel circuit. The implication is that elements of a parallel circuit have the same voltage across them. Lets add a second bulb in series with the first. The voltage going up across the battery is still +1.5V, while the voltage going down across each bulb is -0.75V. Again, the sum is zero. You can take this to any level of complexity during circuit analysis. Find the series or parallel elements and calculate drops around the series part or find the equivalent voltages across the parallel parts, combine that with other techniques such as Kirchoff's current law, and Norton and Thevanin equivalents, and you can analyze any circuit. ANSWER: In a series circuit since the current remains the same for every items the voltage will vary according to ohm law
How many cans on one 15 amp breaker?
Assuming the can lights is all that will be on this 15 amp 120 volt circuit and each one has no more than a 75 watt bulb installed you can install up to 19. This is determined by multiplying the amps x the voltage to get the wattage. 15 x 120 = 1800. Then multiply the 1800 x 80% and you get 1440 which places an 80% load on the circuit which is all you safely want. You then divide the 1440 by 75 which is the wattage of each bulb and you get 19.2. You could add more if you use fluorescent bulbs but someone could come along later and install incandescent bulbs and overload the circuit. So stick with no more that 19 to be safe. Remember this is a 15 amp ciruit so you must use AWG # 14 wire and not #12. If you use AWG #12 and a 20 amp breaker you can have 25 can lights with 75 watt bulbs on the circuit.
How do you reduce voltage in a circuit?
You reduce voltage in a DC circuit with a resistor. If the power demands are high, however, you may need a switching voltage regulator.
When you add a second battery to a series circuit what happens?
Adding a seound battery to a series circuit will increase the voltage, and require less current to keep the lights (if there are any on) as bright. Say you have a 6v battery, then you add another 6v battery. the voltage of the circuit would be 12v
What type of diode circuit is used to add or restore a ac level to an electrical signal?
a clamp
how to use circuit in sentence?
to complete the circuit you have to add 1 light bulb.
What might happen to the bulb if you add too many extra batteries to the circuit?
death 2 the bulb
How would you make a bulb in a circuit shine with a fainter light?
If you add resistance to the circuit the bulb will shine with a fainter light ... the higher the resistance is the fainter it will shine
If you add an extra battery to a circuit containing a bulb how will this affect the bulb?
The bulb becomes brighter unless it is too much till it shot-circuits.
If you add an extra bulb to your series circuit what will happen to the brightness of the bulbs?
The bulb is dim.Because,the voltage is drops in series connection so you add more bulbs in series the last bulb got low voltage that reason for the bulb is dim
Can you mix bulb wattages in a 5 head floor lamp?
There is no electrical reason why this can not be done. Just remember that increasing wattage will add more draw to the circuit. If the circuit that the fixture is on has other loads, the circuit could be overloaded and may trip the breaker.
The current is 0.4 A and the bulb in the circuit is bright. What will happen to the brightness of the bulb if you put another bulb in series in the circuit?
ANSWER: The brightness of both bulbs will decrease. If the bulbs are identical the current will decrease to 0.2 Amps. This is a simple series resistive circuit, the more bulbs you add in series both the amperage and bulb brightness will continue to go down.
Does anything happen to the brightness of the bulb when you add an extra battery to a simple circuit?
We did this experiment in class, the more batteries added, the brighter the bulb will become!
If you add more batteries to a simple circuit will make the bulb?
That will depend on whether they are added in series or parallel.
What will happen to a bulb if you add more batteries to a simple circuit?
It gets brighter and brighter - until it burns out.
How is adding a ammeter to a circuit different from adding a light bulb?
When you add a light bulb, you are adding a load, which performs a function - in this case, it converts electrical energy to light and heat energy. When you add an ammeter, most of the time you intend to measure the current in the circuit, which is the function of the ammeter. Thus the two electrical components differ in their function and does different things when added to a circuit.
Will adding more batteries to a simple circuit will make the bulb?
If you add another battery in series with the first one, then the bulb willglow brighter, and may burn out if you carry things too far.If you add another battery in parallel with the first one, then the brightnessof the bulb won't change, but the battery will last twice as long.
