The electric field generated by a voltage drop of 1 V across an insulator with a thickness of 20 nm can be calculated using the formula E = U/d. In this case, U is the voltage (1 V) and d is the thickness of the insulator (20 nm). Applying the formula, the electric field E is determined to be 50 million volts per meter (50 MV/m). This calculation confirms the correct application of the formula for determining electric fields in a uniform medium.

Calculate the electric field given by a voltage drop of 1 V across an insulator with thickness 20 nm.
2. The attempt at a solution
I am not sure which formula to use in order to obtain the electric field. I think one should use the formula E=U/d, where E denotes the (absolute value of the) electric field, d=20 nm, and U=1V. Is that correct?
