What does null means in java?
Null is a value that any variable can have. It means the absence of a value. However, null can only be assigned to object reference variables; attempting to execute a method on a null variable will cause the JVM to throw a NullPointerError.
What are the readings for the experiment - to convert a galvanometer int ammeter?
A galvanometer is a type of ammeter an instrument for detecting and measuring electric current. A galvanometer can be converted into ammeter by connecting resistance in parallel with it.
If null is compared with null what is the result-true or false or null or unknown?
You mean SQL? NULL = anything IS NULL NULL <> anything IS NULL ... NULL IS NULL = TRUE NULL IS NOT NULL = FALSE
Why potentiometer method is an accurate method for measuring potential difference?
Say 'emf' instead potential difference. Because while measuring the same no current is drawn and just balancing the potential across with the potential drop on the balancing length of the potentiometer wire. While balancing the galvanometer shows null deflection. So no current flows through the galvanometer. A perfect balance with the potential difference (EMF) of a cell with potential drop across that particular length.
Does interchanging the galvanometer ad battery in a wheatstone bridge affect the balance?
No.AnswerWork it out, yourself, from first principles. Start with the assumption that, for the bridge to be 'balanced' (i.e. with no current flowing through the galvanometer), the potential-difference across the galvanometer is zero. It is quite simple.
What does the mid point mean in a graph?
null
Disadvantages kelvin double bridge?
requires manual balancingsensitive null detector or galvanometer is required to detect balance conditionmeasurement current needs to be reasonably high to achieve sufficient sensitivity.
What is the difference between the construction of a moving coil galvanometer and a ballistic galvanometer?
What is the difference between the construction of a moving coil galvanometer and a ballistic galvanometer?
Does a galvanometer have a reversed current or not?
The current is reversed in a galvanometer
Why tangent galvanometer is called tangent galvanometer?
because in tangent galvanometer earth magnetic field and magnetic field of magnet inside galvanometer are perpendicular to each other
What is the null point in pot line in aluminium smelter?
Its a point on the galvanometer where the galvanometer shows no deflection as no current passes through it. Vedanta aluminium operates the world’s biggest aluminium smelter plant of India at Jharsuguda, Odisha. The plant has 1.6 MTPA aluminium smelting capability and a related 3615 MW thermal electricity technology facility. The only Indian plant withinside the global ‘1 Million Tonne’ production and export club, vedanta Jharsuguda is a frontrunner in added aluminium merchandise that discover crucial packages throughout core industries. Since our 1st heat steel sound in March of 2008, our aluminium smelting unit at Jharsuguda has come to an extent to set up itself because it's the world’s biggest single-region plant.
How you convert galvanometer into ammeter in detail?
By attaching a resistance in parallel connection with the galvanometer. Or when a low resistor connected in parallel with galvanometer ,the galvanometer is converted in ammeter. and the resistor is called shunt resistance.
What actors and actresses appeared in Null Sonne No Point - 1997?
The cast of Null Sonne No Point - 1997 includes: Lester Bowie as himself Hartmut Geerken as himself Roscoe Mitchell as himself
What is weston galvanometer?
The weston type galvanometer is a moving coil galvanometer in which a pointer is attached to the coil for measuring deflection due to torque .
Steps in making a galvanometer?
A galvanometer is used to test an electrical current. A galvanometer can be made using a compass and a thin gauge of wire.
Why A sensitive galvanometer cannot be stable?
