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 .
What is used to turn the pointer of a galvanometer?
A small current passes through the coil that actuates the pointer. When you select different ranges on the instrument you are in fact selecting different resistors so that the sensitivity of the pointer is changed.
What causes the loops of wire and the pointer to move in a galvanometer?
The electromagnet's coil is attached to a pointer. When a current is in the electromagnet's coil, a magnetic field is produced. This field interacts with the permanent magnet's field, causing the loops of wire and pointer to rotate.
What does electromagnetism have to do with galvanometer?
A galvanometer is a simple meter that detects the flow of current. A current flowing in a wire causes magnetism around the wire. This is called electromagnetism. Like poles of a magnet repel and opposites attract. The Galvanometer uses these principles in order to move a pointer across a scale.
What is the mouse pointer?
the move pointer
How does the pointer move when the balance nut is tightened?
The pointer is lose.
Is the distance a pointer of a galvanometer moves determined by the amount of magnetism in the loops of the armature?
No, you have to use the reflux integer i=53^-32 which is a constant. This formula will help;
The move pointer is displayed as an?
^ <> v
What to do when in excel worksheet pointer not work as copy pointer or as move pointer?
All you need to do is just press the arrow keys and the cursor will move in the direction of the arrow that has been pressed. If you press and hold the one of the Shift keys at the same time, then it will also select cells as the cursor moves.
The mouse pointer turns to a what whenever you move it outside the worksheet?
the mouse pointer turn to arrow
What is the different mouse pointers?
the move pointer
What is theory of electric meter?
The mechanical pointer meter operates off a slug and a coil to move the pointer
