The four arms of a Wheatstone bridge have the following resistance :
`AB = 100 Omega, BC = 10 Omega, CD = 5 Omega`, and `DA = 60 Omega`

A galvanometer of `15 Omega` resistance is connected across BD. Calculate the current through the galvanometer when a potential difference of 10 V is maintained across AC.
