What is the difference between digital and mercury thermometer?

What is the resistor inside a light bulb?
In an 'old fashioned' incandescent light bulb, the only electrical part inside is the filament wire itself. When you put a meter across a cold bulb and measure the resistance, you're measuring the resistance of the filament. More modern and more efficient artificial light sources, like fluorescent tubes, LED lights and CFLs, have additional electronic components inside the structure of the bulb.

Why galvanometer is connected in wheatstone bridge?
A Wheatstone Bridge is used to measure resistance of an electrical / electronic component. The galvanometer (which was used to measure voltage) has now been replaced by the Multimeter.Both are not used today.AnswerA Wheatstone Bridge has most definitely NOT been replaced by a multimeter! It uses a completely-different method of measuring resistance and is significantly more accurate than a multimeter. The purpose of the very sensitive galvanometer is to detect when the Bridge circuit is 'balanced', by sensing the current (not voltage!) passing through it. When no current flows, the Bridge is balanced.
What measures electrical resistance?
an ohm meter OR multimeter is used to measure the electrical resistance...
What check should be done to an electrical measuring device before attempting to measure electrical resistance?
An electronic measuring device also known as a multimeter is used to check the electrical voltage in homes and industrial areas. The checks that need to be done before a multimeter is used is the to plug the black test lead into the black socket marked com. The red lead plugs into the red socket marked voltage and resistance.
What electrical measuring instrument is used to measure polarity index test?
A low resistance ohmmeter is used
What is an absorption dynamometer?
An absorption dynamometer is an instrument used to measure force, by measuring the energy absorbed via friction or electrical resistance.
What are ohms?
the unit of measure for electrical resistance
What is avo meter?
avometer comes from " avo " and "meter". 'A' means amperes, to measure electrical currents. 'V' means the voltage, to measure voltage. 'O' means ohms, to measure ohms or resistance. finally the meter or unit of measure. often reffered to as AVO meter multimeter or multitester. AVO meter is a device for measuring voltage, current, both AC and DC and electrical resistance.
How do you measure armature resistance practically?
by using measuring meter
What device is used to measure the resistance of a resistor?
You can use a multi-meter to measure resistance. The specific portion of the meter for measuring resistance is called an ohmmeter.
What is the ohm unit used to measure?
Ohms measure electrical resistance. The resistance in ohms is the voltage divided by the current.
What is the difference between digital and mercury thermometer?
Digital thermometers measure electrical resistance and Mercury thermometers measure thermal expansion.
