What else can I help you with?
Why should the connecting wires in a bulb be of low resistance?
This is to avoid energy losses in the connecting wires.
What is the resistance value for LED bulb in 12v DC circut?
The resistance value for an LED bulb in a 12V DC circuit can vary depending on the specific LED bulb used. Generally, LEDs have very low resistance values due to their semiconductor nature. It is more common to use a current-limiting resistor in series with the LED to control the current and prevent damage to the LED.
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
How thickness of wire affects brightness of bulb?
Considering that everything else is equal, ie. glass, incoming wire. If you are talking only about the filament wire that is attached between the Two poles inside the bulb, the answer is friction. The thicker the wire the less resistance it will have and will allow more electricity to pass without creating friction, the friction is what causes the wire to heat up and glow.
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.
If a Christmas lights filment breaks how would you connect it again?
Theres no way without breaking the bulb
If a Christmas lights filment breaks how would you fix it again?
Theres no way to do it without breaking the bulb
Why should the connecting wires in a bulb be of low resistance?
This is to avoid energy losses in the connecting wires.
How to test a light bulb with a multimeter?
To test a light bulb with a multimeter, set the multimeter to the resistance or continuity setting. Touch one probe to the base of the bulb and the other probe to the metal threads at the bottom. If the multimeter shows a low resistance or beeps, the bulb is working. If there is no reading, the bulb is likely burnt out.
What happens to the resistance of the bulb as the current passing through it increases?
Yes but very slightly,because temperature coefficient of bulb element is very low.
What is the resistance of a fuse bulb?
A lamp has two resistances: a 'hot' resistance (its operating resistance) and its 'cold' resistance (its resistance when switched off), and the hot resistance is significantly higher than its cold resistance.You can calculate its 'hot' resistance from its rated power and its rated voltage (assuming that it is being supplied at its rated voltage), by manipulating the following equation, to make Rthe subject: P= V2/RYou will, though, have to measure its cold resistance.
What gives a switch the power to turn light on and off?
The switch its self has no power. When you flip the switch it connects the circuit allowing electricity to flow through to the light bulb. The lightbulb works by creating resistance(the filment) which gives off energy in the form of heat and light. So what gives it power is you :).
Were is the filment on the flower?
it is the part of that flower
What is cold resistance?
That is e.g. the resistance of a cold bulb before the bulb is lighted and heats up.
What gives the biggest resistance 3 volt bulb or 6 volt bulb?
3 volt bulb gives the biggest resistance
How do we calculate the cold resistance of the bulb?
The cold resistance of a bulb can be approximated by measuring the resistance of the filament with a multimeter when the bulb is turned off and at room temperature. The resistance measured in this state can give an estimation of the cold resistance of the bulb. Keep in mind that this value may not be exact due to factors like the temperature coefficient of resistance and the non-linear behavior of the filament's resistance.
