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.
What else can I help you with?
When the switch is closed it means that?
There is a complete path for the electricity to flow. The opposite of an open circuit. If a light switch is on and the light comes on, the circuit is closed. If the switch is turned off, the light goes off because the circuit is open.
If a light bulb is missing or broken in a series circuitwill the other bulb light?
In a series circuit, if a light bulb is missing or broken, the circuit becomes incomplete, and the electrical current cannot flow. As a result, the other bulbs in the series will not light up. All components in a series circuit must be functioning for the entire circuit to operate.
What does green light mean on circuit tester?
it works
What is a seris and a parrel circut?
in a series circuit current flows through each resistor or light bulb and if one item burns out the complete circuit goes dead such were the old fashioned xmas tree lights. They were wire in series and if one light burned out you had to test each light bulb til you found the one burned out to get the whole string to work again. In a parallel circuit each resistor, motor, light bulb has its own ground so if you lost one light in a circuit the rest of them continue to burn.
What happens when you disconnect a light bulb from a series cicuit?
Dear Wiki Questioner, When you disconnect a light bulb from a series circuit, the entire circuit is broken and no electricity can flow around it... so everything else on the circuit looses access to the power source! You can think of a series circuit as a relay race, where the runners are the bulbs and wires (and anything else that is connected to the circuit). If any one of the runners in a relay race is taken out of the race (say by a sprained ankle), the relay gets stuck and the team cannot complete the race (that is to say, the electricity cannot make a complete circuit). Of course, if you plug that runner back into the system, the race continues as usual!
Where is the best place to put an ammeter in the circuit to measure the current going through the light bulb?
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.
What components do you need to make a simple series circuit to light a bulb?
You need a Battery, Light Bulb, Ammeter, Switch.
What will the decrease of the light intensity on an LDR do to the ammeter reading?
The decrease of light intensity on an LDR will cause the resistance of the LDR to increase, which will result in a decrease in current flow through the circuit. As a result, the ammeter reading will decrease.
What are the independent dependent and control variables in series circuit containing 1ammeter a resistor a light bilulb and 3cells?
Independent variable: the number of cells in the circuit. Dependent variable: the current measured by the ammeter. Control variable: resistance of the resistor, type of light bulb.
What happened to the reading of ammeter and voltmeter if the number of dry cells are added in the circuit?
Well, isn't that just a happy little question! When you add more dry cells to a circuit, the ammeter will show a higher reading because there is more current flowing through the circuit. The voltmeter reading will also increase because the total voltage of the circuit will be higher with the addition of more dry cells. Just remember to always paint with light and electricity in your circuits, my friend!
In a series circuit when adding light bulbs does the current change?
Yes. The current is inversely proportional to the resistance. I = V / R where I is current, V is voltage, and R is resistance. Adding light bulbs adds resistance. Current is constant throughout a series circuit; it doesn't change no matter what. Voltage changes.
Why does adding more batteries to a circuit cause an attached light bulb to become brighter?
Adding more batteries increases the voltage across the circuit, which results in a higher current flowing through the light bulb. The increased current generates more heat and light in the bulb, making it appear brighter.
Why will the current flow be different in a heated rear screen circuit than a side light circuit?
the heated rear screen circuit has a higher resistance compared to the side light circuit
What components do you need to make a simple series circuit to light on bulb?
You need a Battery, Light Bulb, Ammeter, Switch.
Will adding light bulbs to a parallel circuit causes all of the light bukbs to shine less brightly?
No. In a parallel circuit, the resistance gets cut in half, so logically the bulbs would do the opposite and get brighter.
If you have three light bulbs on a circuit but all the bulbs have a different electrical path what kind of circuit do you have?
Parallel.
Why is an ammeter also called a tell tale?
There are some applications where using an ammeter is the only way to troubleshoot a problem without tearing apart the entire circuit. It is the only meter setting on the DMM used while the circuit is energized. After calculating the amperage that should flow through the circuit by measuring ohms and volts, an ammeter directly shows any "tell tale" discrepancies between calculated amps and actual amps. Example: In theatre lighting, a volt meter reads 110V on a power circuit, and an ohmmeter reads close to 0 when measuring across a lamp's power connector leads; yet, when connected, the lamp won't light and the breaker doesn't trip. In theory, 110V across a lamp reading 0 ohms should light the lamp. A quick bit of minor surgury and a measure with the ammeter "tells the tale" that very little current is flowing; therefore, one of the digital dimmer packs has probably gone bad -- it will provide a phantom power of 110V with little current. Without the ammeter, one would have to waste time troubleshooting the dimmer itself.
