How much work is required to move an electron through a potential difference of 3.00 volts?

The amount of work required to move an electron is 4.8×10⁻¹⁹ J.

Electric Potential difference: This can be defined as the work done in moving 1 coulomb of electric charge from one point to another in an electric field.

The Formula for potential electric potential energy is given as

W = QV Equation 1

Where W = Amount of work required to move an electron, V = potential difference, Q = charge on an electron.

From the question,

Given: V = 3.00 volts, Q = 1.60×10⁻¹⁹ C.

Substitute these values into equation 1

W = 3(1.60×10⁻¹⁹)

W = 4.8×10⁻¹⁹ J

Hence, The amount of work required to move an electron is 4.8×10⁻¹⁹ J

The required work done to move an electron through a potential difference of 3 volts is 4.80×10⁻¹⁹ J.

Explanation:

Work done: The product of charge and potential difference.

W= q·ΔV.

q= charge

ΔV=potential difference

We know,

The charge of an electron is= 1.6×10⁻¹⁹ C.

ΔV= 3.00 volts.

W= q·ΔV

  =( 1.6×10⁻¹⁹ C )× (3.00 volts)

  =4.80×10⁻¹⁹ J

The work done to move an electron through a potential difference of 3 volts is 4.80×10⁻¹⁹ J.
