A W bulb and a W bulb are connected in series in a circuit Which bulb has the greater current flowing in it?
A series circuit is where there is only one path for the current. As a result, and as a direct consequence of Kirchoff's current law, the current at every point in a series circuit is the same. The two bulbs have the same current flowing through them.
In the circuit shown below with each bulb holding a resistance of 150 ohms how many amps of current are flowing Express your number as a decimal.?
To determine the current flowing through the circuit, you need to know the total voltage supplied and how the bulbs are arranged (in series or parallel). If we assume a standard voltage of 120 volts and that the bulbs are in series, the total resistance would be the sum of the resistances (e.g., for two bulbs, it would be 300 ohms). Using Ohm's Law (I = V/R), the current would be 120 volts / 300 ohms = 0.4 amps. If the bulbs are in parallel, the total resistance would be lower, and the current would be higher; please provide more details for an accurate calculation.
With each bulb holding a resistance of 100 ohms how many Amos of current are flowing?
To determine the current flowing through each bulb, you would need to know the voltage (V) applied across the bulbs. According to Ohm's Law (I = V/R), where I is the current in amperes, V is the voltage in volts, and R is the resistance in ohms, you can calculate the current. For example, if the voltage is 120 volts, the current would be I = 120V / 100Ω = 1.2 A. Without the voltage value, the current cannot be calculated.
Does more current flow into a light bulb than out of it?
No. Although there is a voltage drop across the filament of an incandescent light bulb, the amount of current flowing out is identical to what flows in: current in = current out. That is an important fact to always keep in mind when solving simple electrical circuits: the sum of the currents flowing into a node equals the sum of the currents flowing out of it.
What happens if you take away a load from a series circuit?
As an example imagine a 60 W light bulb running off 120 V. The current will be 1/2 A. Now assume that you put a second 60 W bulb in series with the first. Now the resistance of the single 60 W bulb is 240 Ohms. The 1/2 A flowing through the bulb heats up the filament wire and causes an amount of light to be emitted. Resistance in series adds, so the total resistance for two of the bulbs in series is 480 Ohms and by Ohms law V = I x R, the current through each bulb will be 1/4 amp and hence the bulbs will be less bright.
How much current do light bulbs use up when they are turned on?
When light bulbs are turned on, they typically use up around 0.5 to 1 ampere of current.
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 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.
What happens to the total current provided by the battery as more bulbs are added to a parallel circuit?
The total current provided by the battery increases as more bulbs are added to a parallel circuit. This is because each branch in a parallel circuit receives the full voltage of the battery, leading to more current flowing through each branch as more loads (bulbs) are added.
Compare the current in a 2 light bulbs wired in a series circuit?
In a series circuit, the current passing through each component, like the light bulbs, is the same. This means that both light bulbs would have the same current flowing through them. If one light bulb were to burn out, current flow through both bulbs would stop.
What happens to the ring main as more bulbs are turned on at night?
As more bulbs are turned on in a ring main circuit at night, the total current drawn from the circuit increases. This can lead to a drop in voltage across the bulbs if the circuit is not designed to handle the additional load. If the current exceeds the circuit's capacity, it may trigger protective devices like circuit breakers or fuses, potentially causing them to trip. Additionally, prolonged overloading can lead to overheating and damage to the wiring.

Why do fluorescent light bulbs flicker?
Fluorescent light bulbs flicker because of fluctuations in the electrical current flowing through the bulb. This can be caused by issues with the bulb itself, the ballast, or the electrical connection.
What happens to electrical current and voltage in a parallel circuit as you add more bulbs?
Voltage remains constant; current increases.
What happens to the current in a circuit when one bulb is replaced by two bulbs in series?
current in series always stays the same
What happens to the current measured as more bulbs added?
It is unclear what type of circuit you are referring to, so I'll give both answers.parallel, current increases until too many bulbs have been added, then circuit breaker pops and current drops to zero.series, current decreases and all bulbs dim.
If two light-bulbs are connected in a series circuit and one of the light-bulb's current flowing is 0.5 A what is the current flowing in the other light-bulb?
Current in a series circuit is the same throughout the circuit. Voltages are additive. Voltage in a parallel circuit is the same throughout the circuit. Currents are additive.
