A conductor having a charge of 1 μL has an energy of 0.5 J. is the potential of the conductor?

Initial data: q (conductor charge) = 1 mC (1 * 10 ^ -3 C); W (the energy possessed by the conductor) = 0.5 J.

The potential of a conductor can be expressed from the formula for calculating the energy of a charged conductor: W = 0.5 * q * φ, whence φ = 2 * W / q.

Let’s make a calculation: φ = 2 * 0.5 / (1 * 10 ^ -3) = 1 * 10 ^ 3 V (1kV).

Answer: The potential of the conductor is 1kV.
