Is current greater in thick or thin filament?
more current flows in the 60 W bulb, which means the resistance of the filament is less. why are thick wires rather than thin wires used to carry large currents? thick wires have less electrical resistance and will carry greater amounts of current without overheating.
Does a lamp with a thick filament draw more current?
thick filament has less resistance and will draw more current than a thin wire connected across the same potential difference.
How does the thickness of the filament affect current?
The resistance of a light bulb filament is effected by both length and cross-sectional area. Thicker wires have less resistance. A 120-Watt bulb has a greater current and a smaller resistance. Calculate the resistance and the current of a 7.5-Watt night light bulb plugged into a US household outlet (120 V).
When connected in series which is the current greater the thick lamp filament or the thin lamp filament?
Physics 4-26
| Question | Answer |
|---|---|
| Two lamps, one with a thick filament and one with a thin filament, are connected in a series to a battery. The voltage is greater across the lamp with the | thin filament |
Which will have greater resistance a thinner filament or a thicker filament?
in a domestic light bulb) the thicker the filament the lower it’s resistance and so less energy is converted into heat – the filament is dimmer. Brighter filaments are thinner, have higher resistance and so heat up more -> brighter.
Which filament is brighter?
Dual filament bulbs like the # 30-90-157 have two different filaments. One filament is of a different resistance value, and thus makes a brighter light. but the brake and turn signal filament would be the brighter of the two.
What happens when current flows through a lamp filament?
A filament lamp is a common type of light bulb. It contains a thin coil of wire called the filament. This heats up when an electric current passes through it, and produces light as a result. The resistance of a lamp increases as the temperature of its filament increases.
When electrons flow in a thin lamp filament they experience friction What is the practical outcome of this?
when electrons flow in a thin lamp filament, they experience friction. what is the practical outcome of this? heat and light. how much current is drawn by a 60 omega resistor when a voltage of 12 v is impressed across it?
How does the size of a filament affect its glow?
What happens when two light bulbs are connected in series?
In series, both bulbs have the same current flowing through them. The bulb with the higher resistance will have a greater voltage drop across it and therefore have a higher power dissipation and brightness. In parallel, both bulbs have the same voltage across them.
Which has the thickest filament a high resistance or a low resistance bulb?
2. Which has the thickest filament – a high-resistance or a low-resistance bulb? A low-resistance bulb.
How thick is a light bulb filament?
The filament in a light bulb is made of a long, incredibly thin length of tungsten metal. In a typical 60-watt bulb, the tungsten filament is about 6.5 feet (2 meters) long but only one-hundredth of an inch thick.
