Question
Show that units of V/m and N/C for electric field strength are indeed equivalent.
Step 1
The units for these quantities are joules (J) for energy, coulombs (C) for charge, and volts (V) for potential difference. Therefore, we can write the relation between these units as $J = CV$. Show more…

Show that 1 V/m = 1 N/C and thus that the two units used to describe electric field are consistent. Hint: Start with the definition of V, where 1 V = 1 J/C.
