How bright is the bulb when a shorter wire is used?
Depending on the length of the wire difference between the shot and long wire, in technical fact the bulb would be brighter if a shorter wire was used, but not that much brighter. Energy is used up as it travels along wires.
What could be a source of resistance in a household electric circuit?
Heat
Why does the resistance of a filament bulb depend on the current in the bulb?
The resistance of a piece of wire changes with temperature. In a filament bulb the wire is heated to about 3000 degrees C so a large change in resistance can be expected. A 240 v 105 w halogen bulb has a cold resistance of 35 ohms, but when running its resistance is 549 ohms.
A 9.0 volt battery connected to bulb. if a current of 0.25 Amps flows through bulb what is the resistance of bulb?
V = IR Voltage = Current * Resistance so 9 = 0.25 * R Hence R =36 Ohms
What do the wires in the middle of a light bulb do?
The filament is made of tungten and these 'wires' (filament) conduct electricity.
How does the flow of electricity through a light bulb connected to a battery with wires affect the brightness of the bulb, and what factors should be considered in this scenario?
The flow of electricity through a light bulb connected to a battery with wires affects the brightness of the bulb. Factors that should be considered in this scenario include the voltage of the battery, the resistance of the wires, and the wattage rating of the light bulb. Increasing the voltage or wattage will make the bulb brighter, while increasing resistance will make it dimmer.
What OF parts of circuit?
Simple parts of a circuit are switches, light bulb, battery and connecting wires.
What differene will different length or thichnesses of wire have on the brightness of a bulb?
Thicker or shorter wires will have lower resistance, allowing more current to flow and increasing the brightness of the bulb. Thinner or longer wires will have higher resistance, reducing current flow and dimming the bulb. Ultimately, the length and thickness of the wire will impact the overall electrical resistance in the circuit, affecting the brightness of the bulb.
Is it sensible for the TV to be connected in series with the light bulbs?
Connecting light bulb is equivalent to connecting a resistance. If you have connected light bulb, there will be some voltage drop across it and your TV may not get sufficient voltage. However if resistance is not big enough, than it wont have any effect.
What is inside a torch?
Inside a torch ther is a bulb a cell and a swith. with some wires connecting them. it is a simple series circuit.
What are the parts of an electric bulb?
The parts of a light bulb are the glass envelope, mixture of inert gases at a lower pressure, and a screw cap. Inside of the light bulb is the coiled tungsten filament, support wires, glass fuse enclosure, connecting wires, and the electrical contact.
What materials use for bulb?
A Light bulb uses glass for the casing, brass/aluminium for the screw or bayonet mount, tungsten for the filament, copper alloy for connecting wires and porcelain for insulation.
How do you stop blinking Christmas lights?
Typically, you find the bulb with the red tip and replace it with a regular bulb. The red tipped bulb is a flasher bulb. Unfortunately, not all flasher bulbs are marked with a red tip. In that case (assuming your lights are controlled by a flasher bulb and not some other method), you'll need to go through each bulb to find the bulb that doesn't look like the others. A regular bulb will have two connecting wires and a filament between them. The flasher bulb has an extra wire touching one of the connecting wires. I'd expect that the flasher bulb would be the first or last bulb on the string.
What 2 things do you need for a current to flow?
To create a current flow, you need a closed circuit that allows the movement of charged particles, such as electrons, and a potential difference across the circuit that drives the flow of these charged particles.
What needs to be complete for a bulb to light up in a ciruit?
What needs to be complete is the circuit from the battery to the bulb, then the other wire from the bulb to the other side of the battery.If it is from an outlet rather than a battery, the circuit starts and finishes with the live and neutral pins at the outlet.
Which has the thickest filament - a high-resistance or a low-resistance bulb?
A high-resistance bulb typically has a thicker filament compared to a low-resistance bulb. The thicker filament in a high-resistance bulb can withstand the greater heat generated by the increased resistance, resulting in a longer lifespan for the bulb.
What experiments suggest that wires have essentially zero resistance?
Think of this as two scenarios. First, we have one blub, one battery, and two wires in a closed circuit, and the bulb lights up. Next, think about what would happen if we added a couple more wires to the circuit. The bulb would still light up, just as brightly, meaning that the new wires are not increasing the amount of resistance. This means that the wires are not slowing down the flow of charges.
