Why the zero of the ohmmeter scale is usually at the right end of the scale and reading increase towards the left?

Because the meter is actually measuring the current through the resistor, and
the two quantities ... current and resistance ... are inversely proportional.
So when the meter measures more current, it has to read less resistance, whereas
higher resistance will result in less current. So the numbers for resistance have to be
printed "backwards" on the meter scale.

The ohmmeter differs from other types of meters in that it has its own?
Electric supply, usually a battery.
What is genetic gain?
is the amount of increase in performance that is achieved through artifical genetic improvement programs. This is usually used to refer to the increase after one generation has passed.
How to identify the anode and cathode of DR 25 diode?
The cathode of a diode is usually indicated with a band. In the absence of the band, consult the datasheet. Alternatively, use an ohmmeter that generates more than 0.7 volts at low current (a diode checker) and check conductance. The diode will conduct when the anode is more positive than the cathode.
Is The carrier frequency is usually lower than the modulating frequency?
when the frequency is low , energy will be obviously low. To increase the energy of the signal we need to increase the frequency. This is achieved by multiplying the message signal with the carrier signal (with high frequency).
Where are robots used in the society?
Usually in factories. In 5-10 years the robot population will increase. Department of Defense and NASA are also big on robotics
What tool can be used to test for electrical conductivity?
The easiest way is to use an Ohmmeter. This function is usually built into most multimeter that can be bought at any hardware store. An Ohmmeter measures the electrical resistance of a material. The lower the number the more conductive that material is. If the Ohm reading is above the maximum reading on the meter then their is infinite resistance which means that the material is not a conductor of electricity.
The ohmmeter differs from other types of meters in that it has its own?
Electric supply, usually a battery.
The will measure resistance only?
The ohmmeter is usually used to measure the resistance of a given wire only.
What instrument measures voltage?
Resistance is measured with an ohmmeter. A link is provided to a brief article on the ohmmeter posted at Wikipedia.Note that it is unusual in this day and age to have a device that will measure ohms and nothing else. The ohmmeter is usually included among the functions of a multimeter, and usually a digital multimeter or DMM.
Can the word reading refer to required reading?
In school the word reading usually does mean that it is required reading. At home no reading is usually voluntary and done mostly for pleasure or curiosity.
What is infinity on a multimeter?
If is being used as an ohmmeter it usually means an open circuit. A switch may be open, or a wire is broken (not a short circuit)
What reading level are the R L stine books?
R.L. Stine's books are usually targeted towards middle-grade readers, typically around the ages of 8-12. The reading level for his books can vary, but they generally fall within the range of grades 3-7.
