What else can I help you with?
What is the best way to ensure that a 40 watt bulb and a 60 watt bulb have the same voltage applied to them?
Light bulbs connected in parallel automatically have "the same voltage applied to them".
What makes a dc bulb different from an ac bulb?
The voltage source that is applied to them is the difference between AC and DC light bulbs.
Do you add more bulbs to make a bulb shine brightly?
Adding bulbs will not make the first bulb shine more brightly. Using Ohm's law, E = I x R , increasing the voltage will increase the current and the bulb will burn brighter. Of course, increasing the voltage will also burn out the bulb sooner. Also, if you add bulbs to a parallel circuit, the voltage will drop marginally, causing the first bulb to shine slightly more dimly! The voltage will not drop in a parallel circuit it remains the same. If this were true then every time you switched on a light in your house that was on the same circuit, you would see the other lights dim as the voltage dropped. I have never seen this phenomena happen as long as I have been in the trade. Since the input voltage is set to a specific value it was a hypothetical answer "Not more bulbs- only higher voltage or lower filament resistance will make the bulb shine brighter. I said 'drop marginally'. In a well specified system, the voltage drop will not be noticable but it does happen. Try switching on a kettle or big heater in the same circuit as a desk lamp, you will see the lamp dim slightly.
Can 120v 20w bulb be used in low voltage 12 volt system?
No, a 120V 20W bulb cannot be used in a 12V system. The bulb is designed to operate at 120V, and using it in a 12V system would likely cause it to burn out or malfunction. It is important to use bulbs that are designed for the specific voltage of the system.
What happens to the current through bulb 2 if the switch s is opened?
If switch S is opened, the current through bulb 2 will decrease and eventually stop flowing because the circuit is broken. Bulb 2 is connected in parallel to bulb 1 and both bulbs have the same voltage across them, so when the circuit is opened, current stops flowing through both bulbs.
What is the reason for bulb becoming dim when connected in series?
the voltage across it is reduced, the voltage is shared with other bulbs
Can one cell in a circuit light two bulbs?
Yes, one cell in a series circuit can light up two bulbs. However, the brightness of each bulb may be reduced compared to if only one bulb were connected due to the voltage being split between the bulbs.
How is voltage determined on a light bulb?
Voltage on a light bulb is determined by the amount of electrical potential difference applied across its terminals. The higher the voltage, the brighter the bulb will shine. Light bulbs are typically rated to operate at a specific voltage, such as 120V for standard household bulbs.
What happens to the voltage as more bulbs are added in series?
The voltage in a series circuit is divided among the bulbs, so as more bulbs are added in series, each bulb receives less voltage. This causes the brightness of each bulb to decrease compared to when fewer bulbs are present.
Suppose in a circuit with 2 bulbs the resistance of bulb 1 is greater than that of bulb 2. how will the voltage across the two bulbs compare?
if the resistance of bulb A is 2x that of B then there will be twice as much voltage across it (ratio 2:1 ). both voltages shall equal the system voltage assuming they are in series and there are no other components in the circuit if the bulbs are in parallel the voltage across them will be equal and that of the system
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 higher voltage burn the fluorescent bulbs?
it all depends on the voltage the light bulb can sustain.
The voltage for 4 bulbs in a circuit?
The circuit voltage or the resistance of the individual bulb is needed to answer this question. Divide the total power (400 W) by the supply voltage.
Why are two bulbs in parallel bright when you build a parallel circuit with two bulbs a one d- cell battery?
Two bulbs in parallel are brighter than the same two bulbs in series, given the same potential voltage, because there is twice the available voltage to each bulb.
Why do bulbs get fused?
Bulbs can get fused due to various reasons such as power surges, overheating, poor electrical connections, or if they are incompatible with the voltage supply. When a bulb fuses, the filament inside breaks, causing the bulb to stop functioning.
How does the brightness of each bulb in a parallel circuit compare to the brightness of the bulb in a series circuit?
In a parallel circuit, each bulb receives the full voltage of the power source, so all bulbs shine at their full brightness. In a series circuit, the brightness of each bulb decreases as more bulbs are added because the voltage is shared among all bulbs.
How can you connect bulbs in series?
A Bulb can be connected in a series in such a way that the energy source which is applied want to flow equally across the bulbs connected in series. A Bulb has to knobes or holds in which we supply the power. Assume one knob as a positive voltage absorbing source and other has a negative voltage absorbing source. When we connected in such a way that we can apply the voltage continuously in which the bulb will blow easily. When two or more bulbs are connected in series like end of the knob of one bulb i.e., negative to the next positive of the next bulb in series and negative of second bulb to the positive of the third bulb. Then the voltage splits equally across the bulbs connected.
