What instrument measures the height of a desk?
A heightometer.
What is the instrument called that measures current?
The instrument used to measure electrical current is called an ammeter, which is actually a shortened form of 'amp meter'. The current is measured in amperes. In scientific labs, a much more sensitive instrument called a galvanometer is used to measure very small currents.
What is the angle between lines of force and equipotential lines in an electrical field?
The angle is a right angle.
What instrument measures both ac and DC?
hot wire ammmeter or a moving iron ammeter will work for ac and dc.
What is Grounding and shielding in electronics instrument?
in an electric circuit, it is treated as a reference from which other voltages can be measured. also it acts as a common return path of electric current leakages
What is Equipotential lines in electric field?
Equipotential lines in an electric field are imaginary lines that connect points having the same electric potential. Along these lines, no work is required to move a charge between the points, as the electric potential is the same. Equipotential lines are always perpendicular to electric field lines.
What is a ammet?
An instrument that measures electric current in amperes.
Can two different equipotential lines cross each other?
No, two different equipotential lines cannot cross each other. Equipotential lines are points in a space at which the electric potential has the same value. If two equipotential lines were to cross, it would mean that the electric potential at that point has two different values, which is not possible according to the definition of equipotential lines.
How are equipotentials lines oriented with respect to electric field lines?
Equipotential lines are always perpendicular to electric field lines. This is because equipotential lines represent points in a field with the same electric potential, so moving along an equipotential line does not change potential. Thus, the electric field lines, which point in the direction of the greatest change in potential, intersect equipotential lines at right angles.
What instrument measures electric potential?
A voltmeter is the instrument that measures electric potential. It is typically connected in parallel to the circuit or component being measured to determine the voltage difference between two points.
What instrument measures electric current in a circuit?
An ammeter is the instrument that measures electric current in a circuit. It is connected in series to the circuit to measure the flow of current through it.
Why aconductor is an equipotential surface?
A conductor is an equipotential surface because the electric field inside a conductor is zero in electrostatic equilibrium. This means that all points on the conductor have the same electric potential, making it an equipotential surface. Any excess charge on the conductor redistributes itself to ensure this equal potential.
What quantity measures the galvonometer?
A galvanometer is a type of ammeter: An instrument for detecting and measuring electric current.
What instrument measures current in an electric circuit?
An ammeter is the instrument used to measure current in an electric circuit. It is connected in series in the circuit and provides a reading of the amount of electric current flowing through it.
Why are equipotential lines perpendicular to the insulator mapped?
Equipotential lines are perpendicular to the insulator surface because the electric field lines are always perpendicular to the equipotential lines in electrostatic equilibrium. This relationship ensures that there is no component of the electric field tangent to the insulator surface, which would cause the charges to move. As a result, the charges remain at rest on the surface of the insulator.
What does equipotential mean?
Equipotential refers to a surface where all points have the same electrical potential. In physics, this means that the work done in moving a charge from one point to another along that surface is zero. Equipotential surfaces are used to visualize and analyze electric fields.
What are equipotential lines?
A uniform electric field exists between parallel plates of equal but opposite charges.
