What else can I help you with?
Why is there zero current when a light bulb burns out?
there is no voltage and resistance
What is the current of zero watts bulb?
zero
Does the light bulb use up current when it is turned on?
Yes, the light bulb uses current when it is turned on.
What is bulb and its proccess?
A light bulb is an electric light that uses the process of a filament wire that is heated to produce an electrical current. When the electrical current passing throught the light bulb it produces light.
How do you work out the current of a light bulb?
You can use Ohm's Law to calculate the current of a light bulb by dividing the voltage across the light bulb by its resistance, which is typically provided on the bulb itself or its packaging. The formula is: Current (I) = Voltage (V) / Resistance (R).
What is the starting and finishing energy of a light bulb?
Zero,because the distance has no affect to convert electric energy into light energy.
What has to happen for the bulb to light up?
To light up, the bulb needs an electrical current flowing through it. This current is typically provided by connecting the bulb to a power source, such as a battery or outlet. Once the current flows through the bulb's filament, it heats up and produces light.
Can a bulb light if electricity doesn't get to the bulb?
No, a light bulb will not light up if electricity does not reach it. Electricity is required to flow through the filament in the bulb to generate light. If there is no electrical current, the bulb will not illuminate.
Does current direction matter when lighting a light bulb?
No. In fact, if the light bulb is powered by alternating current (AC), as almost allhousehold lights are, then the current is changingdirection 100 or 120 times asecond anyway.
Is a light bulb an insulator or conductor?
It is a conductor, but the filament is a resistor : as current flows through the filament, some of the energy is released as heat and light.
Is a light bulb an electromagnet?
No, a light bulb is not an electromagnet. A light bulb contains a filament that produces light when current flows through it, whereas an electromagnet is a device that produces a magnetic field when current flows through a coil of wire.
Is a light bulb is a kind of lever?
No. A light bulb is a bulb that contains a filament that gets hot when electric current is passed through it.
