A galvanometer gives full scale deflection with \( 0.006 \mathrm{~A} \)
WV current. By connecting it to a \( 4990 \Omega \) resistance, it can be converted into a voltmeter of range 0-30 \( \mathrm{V} \). If connected to a \( \frac{2 \mathrm{n}}{249} \Omega \) resistance, it becomes an ammeter of range \( 0-1.5 \) A. The value of \( n \) is.
