it study's Saturn and it's rings. it has instruments on it to measure it's magnitic feild.
I assume you are referring to methods of measuring small value resistances, as in locating short circuits on a PC card. Two probe is the method used by standard ohm meters. This works OK for most resistance values, as the resistance of the leads & probes is much lower than the resistance being measured. But when the resistance being measured gets very tiny (e.g. a few milliohms) it fails as the resistance of the leads & probe are of the same order of magnitude and are in series with it. Four probe solves this problem by using two probes connected to a current source to drive the resistance and a separate two probes connected to a precision voltmeter calibrated in milliohms. The voltage drop in the leads due to the test current does not get measured by the calibrated voltmeter, as it does in two probe method. There is no voltage drop in the measurement leads as the voltmeter is high impedance.
yes voyager 2 is a space probe
Titan, by the Huygens Probe, which was part of the Cassini-Huygens Probe.
The Mariner10 space probe and the Mercury Messenger space probe.
Resistivity is a constant for a material as opposed to resistance which is dependent on size considerations. This is analogous to specific heat capacity and heat capacity. It can be said that resistivity is more useful for comparison because other factors (size) have been accounted for.In the case of using the four-probe method to measure the thickness of a thin film:ρ = (V/I) x (thickness of film) x (correction factor)We measure the current and voltage using the four-probe method, from which we can get the resistance between the probes. Knowing the resistivity, which is constant for the material and can be obtained from sources such as books, will enable us to relate the resistance to the dimensions of the film.
You cannot determine band gap by four probe method.
A pH probe is a device used to measure the acidity of a solution.
the question is wrongfour prob is better than two prob method as it eliminates the effect of wire imbedance as well as contact resistance
Sigmund Freud, a doctor from Vienna, devised a method called psychoanalysis to probe deeply into a patient's memory.
Air Probe.

A temperature probe is a digital thermometer.
One can purchase a current probe from the tek website. One can also purchase the current probe from Amazon. One can use the current probe to measure circuit.
Psychotherapy.
You can measure the thickness with an optical microscope (look at a crossection) or an ultrasonic probe.
Coz in this expermnt oven containing four probes is used to maintain the continuity with crystal
