List of top Physics Questions on Potential Difference

A charge is moved from point A to a point B. The work done to move unit charge during this process is called \dots

The instrument to measure potential difference is

In the figure, the potential difference between A and B is:

An electron is accelerated from rest through a potential difference of 200 V. The de Broglie wavelength associated with this electron is _____ nm. (Rounded off to 2 decimal places) (Planck’s constant = $6.6 × 10^{-34} J s, 1eV=1.6 × 10^{-19} J$, mass of an electron = $9.1×10^{-31} kg$)

The potential difference to accelerate an electron was quadrupled. By what factor does the de Broglie wavelength of the electron beam change?
