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.

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

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.

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 is the null point in pot line in aluminium smelter?

The null point in a potline of an aluminium smelter refers to the point at which current distribution across the electrolytic cell is at its minimum, indicating the least amount of aluminium production in that specific cell. Optimizing the positioning of anodes and cathodes in relation to this null point is crucial for maximizing efficiency and reducing energy consumption in the smelting process.

What is effect of interchanging the galvanometer and driver cell in meter bridge?

Interchanging the galvanometer and driver cell in a meter bridge would reverse the deflection of the galvanometer. The direction of current through the bridge wire would also change, affecting the balance point. The new balance point will now represent a different ratio of the unknown resistance to the known resistance.

What is galvanometer constant and how to find it?

The galvanometer constant is the factor that relates the deflection of a galvanometer to the current passing through it. It is usually given as the current required to produce a unit deflection (such as one full-scale deflection) on the galvanometer. To find the galvanometer constant, you can pass a known current through the galvanometer and measure the corresponding deflection, then calculate the constant as the current divided by the deflection.

What is null point in C programming?

I'm going to go out on a limp here, and guess you mean "Null Pointer." Well, it's a pointer to nothing. For most systems, it's 0, but rather use NULL instead.

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.

Why do you need to set a galvanometer to 0?

Zero is the normal position of the galvanometer when there is no detection in process.
