The term electric potential is defined as the amount of work done by the unit charge in moving from one point to another against electric field.

The electric field obtained by the relation:

$\stackrel{鈫�}{E}=-\stackrel{鈫�}{鈭�}V$

Taking integration on side and taking limit from

$$\begin{gathered} {鈭�}_A^{B}dV=-鈭�Edr \\ {V}_B-V_A=-鈭�0dr+C \\ {V}_B-V_A=C \\ {V}_B-V_A=C \end{gathered}$$

Sea water is good conductor of electricity because sea water has many types of salt. The high electric potential charge of ship causes phenomenon 鈥淪t. Elmo鈥檚 fire鈥�. The tip is long and sharp so phenomenon 鈥淪t. Elmo鈥檚 fire鈥� occur at tip. The molecules of air will ionize that鈥檚 why the effect most pronounced when the masts are wet.
