What is the difference between an ohmic resistor and a non-ohmic resistor?
A non-ohmic resistor doesn't have a constant resistance. A ohmic resistor has a constant resistance.
What is the resistor inside a light bulb called?
the wire in your light bulb is a resistor :)
Is a ceramic resistor ohmic?
yes
Is a light dependent resistor ohmic?
In some circumstances a filament bulb is used as a variable resistor. As the filament heats up, its resistance increases. This effect is used in some automatic gain control circuits; as the signal level increases, the changing resistance of the bulb can modify the feedback level in order to hold the level constant.
What is the resistor in an incandescent light bulb called?
It is the filament.
What is an example of an ohmic resistor?
i give the ans why iam asking you
What is the difference between resistor and metrosil?
Resistors are ohmic and fixed whereas metrosils are non ohmic and variable - version of a varistor.
What device uses a resistor to transform electrical energy into light and heat?
Among others, the filament of an incandescent light bulb is a resistor- which gives off heat and light.
How do you use a light bulb as a resistor when charging a capacitor?
connect the light bulb to the positive wire like a inline fuse and then connect the wire to the battery it should just burn out the bulb
How do you built a very simple circuit?
wire a resistor across a battery. that is about as simple as it gets. the resistor could be an incandescent light bulb.
What is the function of a resistor in a light bulb?
Most light bulbs don't have resistors; they are resistors. The filament introduces resistance as part of its action. The resistance is what makes it glow. Usually, if you use a resistor with a light bulb or other lighting device (neon tube, LED, etc), it is external. Its purpose is to reduce the voltage to match the requirements of the bulb. For instance, with a 50 ohm resistor, you could probably use a flashlight bulb with a 9 volt battery.
Is it correct to say that a bulb in a circuit is a resistor?
Yes it is. The filament in a standard incandescent bulb is a type of resistor. An incandescent light bulb contains tungsten which reduces electricity and converts electricity to heat and light. All incandescent bulbs are resistors, but only a fraction of resistors are bulbs. If you want to see if a bulb is a resistor, try adding another bulb in series without changing the voltage. Both bulbs will be very dim. Another way to test this is to get a multimeter and set the meter to the resistance setting. If you get any value other than zero, then it is functioning as a resistor.
