Frequent question: Which of the following Cannot be the unit of electric potential difference?

Which of the following is NOT unit of electric potential difference?

Option c) Newton/Coulomb : Force per unit charge which is electric field. Hence, option c) is not a unit of electrostatic potential. Option d) Newton-metre/Coulomb: Newton-metre is Joule. Hence Joule / Coulomb is a unit of electrostatic potential.

What is the unit for electric potential difference?

The standard metric unit on electric potential difference is the volt, abbreviated V and named in honor of Alessandro Volta. One Volt is equivalent to one Joule per Coulomb.

Which of the following can be unit of electric potential?

In the International System of Units (SI), electric potential is expressed in units of joules per coulomb (i.e., volts), and differences in potential energy are measured with a voltmeter.

Which of the following Cannot be calculate the electric potential?

If the electric potential is given, which of the following cannot be calculated? Explanation: Using potential, we can calculate electric field directly by gradient operation. From E, the flux density D can also be calculated. Thus it is not possible to calculate energy directly from potential.

IMPORTANT:  Do modern electrical cars use DC motors?

Which one of the following is not a unit of electric field?

Therefore, the unit which is not a unit of electric field is $J,{{C}^{ -1}}$. Hence, the correct option is (B). Note: Electric field is different for different types of conductors.

Which of the following is not a unit of electric current?

Ampere per second – It is not the unit of charge.

Which of the following is unit of potential difference?

Units of potential difference are joules per coulomb, given the name volt (V) after Alessandro Volta. The familiar term voltage is the common name for electric potential difference.

What is the SI unit of electric potential and potential difference?

The SI unit of potential or potential difference is Volt. One Volt may be defined as the one joule of work-done to move a charge of one coulomb.

Why electric potential and potential difference have the same unit?

It is the work done per unit charge to move a unit charge from one point to another in an electric field. Electric potential difference is usually referred as Voltage difference. The SI Unit of Electrical potential difference is same as the electric potential, i.e; Voltage or Volts.

What is negative gradient of electric potential?

While the magnitude of the electric field is equal to the gradient of the electric potential, the electric field points in the opposite direction of the gradient of the electric potential, and thus →E=−→∇V.

What is equipotential surface Class 12?

Equipotential surface is a surface where all the points lying on the surface have the same electric potential. This means that a charge will have the same potential energy at every point on the equipotential surface.

IMPORTANT:  Do ions in solution conduct an electric current?

What is the electric field intensity?

The electric field intensity at a point is the force experienced by a unit positive charge placed at that point. Electric Field Intensity is a vector quantity. It is denoted by ‘E’. Formula: Electric Field = F/q. Unit of E is NC1 or Vm1.
