A Carey-foster's bridge is a modified version of the meter bridge (wheatstone bridge or potentiometer). It can be used to find out the average resistance per unit length of the meter bridge wire and hence find out the unknown resistance. It is more accurate and more sensitive than a meter bridge.
A tachometer and an auto-meter is an instrument measuring the rotation speed of a car or a motor. An auto-meter is more accurate and reliable than a tachometer.
A good quality analogue instrument is probably as accurate as a digital instrument, but the digital instrument is more robust, has no movement so is not affected by gravity, and is easier to read.
more accurate
There is no great difference between between the two in principlebut,In a Carey foster's bridge there is no end resistance whereas in the case of a metre bridge end resistance afffects our readings.Hence Carey foster bridge is more accurate than metre bridge .Carey foster bridge can also measure low resistance and high resistance but a metre bridge cannot do so.
No, they are simply a different unit of measure.
A vernier caliper.
5000 hz....the sound will be more clear??
the one that had smaller least count wil be more accurate
True
Probably because the meter stick is not accurate enough to measure the small amount of expansion of the rod. You need something smaller and more accurate.
