Noting null points with both direct and reverse current helps ensure the accuracy and consistency of the measurements. By using both current directions, any errors or inconsistencies in the testing equipment or method can be identified and corrected, leading to more reliable results.

What can change alternating current to direct current?

A rectifier is used to convert alternating current (AC) to direct current (DC). The rectifier allows current flow in one direction only, converting the back-and-forth flow of AC to a constant flow in DC circuits.


What effect does an increase in current have on voltage?

That depends on the circuit - but note that in almost all real circuits the current is the dependent variable - you control the voltage and the current sets itself.


Is a electric current a matter or a energy?

Mainly energy. Note that the electric current involves movement of electrons or other particles that are matter; however, the electric current "is" not so much the electrons (they exist whether there is a current or not; it is more precise that the current "is" the electrons' movement. Although even this may be an over-simplification.


Write a brief note on moving coil galvonameter?

A moving coil galvanometer is a device used to measure small electric currents. It consists of a coil of wire suspended in a magnetic field, which causes the coil to move when a current is passed through it. The movement of the coil is proportional to the strength of the current, allowing the device to provide a measurement of the current passing through it.


How will you note the direction of current in Kirchhoff's law?

In Kirchhoff's circuit laws, the direction of current is typically specified arbitrarily when analyzing a circuit. When writing Kirchhoff's equations, if the assumed direction of current for a particular branch is opposite to the actual direction, it will be reflected as a negative value in the equation. The overall goal is to ensure that the mathematical relationships accurately represent the behavior of the circuit.

Give note on ac and dc voltages?

one note on Dc, and AC voltages? sure A DC is a Direct current, which means more accuracy and power. The device using DC power will maintain its action for longer with more accuracy. Whilst AC is commonly used for lights and other unimportant devices. That's the first note i could come up with. ------------------------ DC is direct current which as the name implies, the electrons (of the current) flow in ONE direction. AC is alternating current, which as the name implies, the current alternates and has a "useable/definable" frequency. AC has no definite terminal (Positive or negative) as the direction of the current always changes. This frequent switching can be seen as a sine wave.


Is the word note a direct object?

No, the word "note" is not a direct object. In the sentence, it can function as either a noun or a verb but not a direct object. A direct object is a noun or pronoun that receives the action of a verb.


Who are the people on the current Australian banknotes?

Australian banknotes are now made of a polymer compound with holographic windows and other gadgetry to foil counterfeiting. Australia puts famous or historically significant Australian identities on its banknotes. Current Australian banknotes are as follows - The first and current polymer Five Dollar note released between 1992 and 1997, and from 2002 onwards, had Queen Elizabeth II on the front, and a design showing the new and old Parliament Houses in Canberra, ACT on the reverse. The second and still current polymer Five Dollar note released as a Commemoration of Federation in 2001, had Sir Henry Parkes (politician) on the front, and Catherine Helen Spence (Writer and Suffragette) on the reverse. The first and current polymer Australian Ten Dollar note released from 1995 onwards, has Andrew Barton (Banjo) Paterson (balladist & journalist) on the front and Dame Mary Gilmore (poet & human rights campaigner) on the reverse. The first and current polymer Australian Twenty Dollar note released from 1994 onwards, has Mary Reibey (ex-convict & pioneer business woman) on the front and Rev John Flynn (pioneer of world's first aerial medical service) is on the reverse. The first and current polymer Fifty Dollar note released from 1995 onwards, has David Unaipon (Inventor, preacher & author) on the front, and Dame Edith Cowan (Social worker, politician & feminist) on the reverse. The first and current polymer Hundred Dollar note released from 1996 onwards, has Dame Nellie Melba (Opera singer) on the front and Sir John Monash (WW1 General) on the reverse.
