How can a non electrical quantity like temperature be measured electrically?

Using your example - A temperature probe consists of a bi-metal strip (say - copper on one side and aluminium on the other) - glued together) When the probe encounters a change in temperature, one side of the strip expands or contracts quicker than the other side (due to the different expansion properties of the metals) this induces a minute amount of resistance change in the sensor, which is converted into a readable result by electronic circuitry.

How close is your estimated value to be measured temperature of the water?
Depends on you
What is temperature coefficient for insulator?
"Temperature coefficient" means, how does a certain physical quantity vary, depending on the temperature. In this case, the physical quantity in question is probably the electrical resistance, or the electrical resistivity.
What the standard unit used to express a quantity of charges?
The unit of measurement for the quantity of an electrical charge is called an electrometer. The quantity of charge can also be measured in directly by a ballistic galvanmotere.
What is temperature co-efficiant?
It means how much some quantity (for example, electrical resistance) changes as a function of temperature.
What is temperature co-efficient?
It means how much some quantity (for example, electrical resistance) changes as a function of temperature.
What is the physical quantity measured by an voltmeter?
An ammeter measures the amount of current flowing through an electrical circuit. It measures amperage.
What is a nonphysical quantity?
a physical quantity can be measured, like mass; a nonphysical quantity cannot be measured, like feelings or happiness
Why is electric measured in voltage?
Actually, some characteristics of electricity are measured in voltage. Electrical quantity is measured in kilowatt hours, or kilojoules/hr. To answer your question more specifically, that particular unit of measurement (which corresponds, more or less, to electrical "pressure") is named in honor of Alexander Volta, a pioneer in the study of electricity.
Is temperature a scalar quantity or vector quantity?
temperature is a scalar quantity................
What it means to measure?
If something is measured, it means a quantity is established by some means. This could be size, weight, temperature, speed, and so on.
What is the constant electrical quantity in a series connection and a series-parallel connection?
constant electrical quantity-series connection -current constant electrical quantity-parallel connection - voltage
What are the 7 fundamental quantities and their definitions?
QUANTITY Name Symbol Definition Mass (m) The measure of the quantity of matter that a substance possesses Mass is measured in grams (g) or kilograms (kg) Lenght (l) Time (t) Current (I) The flow of charge in an elctrical circuit. Current is measured in Ampere (A) Temperature (T) Temperature is the measure of the hotness (or coldness) of a body. It is commonly measured in degrees celsius or kelvin (K)
