What shunt resistance must be connected across a galvanometer of 50.0Q resistance Which gives full-scale deflection with 2.0 mA current, to convert it into an ammeter of range 10.0 A?

Explanation

To convert the galvanometer into an ammeter of range 10.0 A, a shunt resistance (Rs) must be connected in parallel with the galvanometer. The formula to calculate the required shunt resistance is:Rs = (G - 1) * RgGiven:Galvanometer resistance (Rg) = 50.0 ΩDesired full-scale deflection current = 10.0 AGalvanometer full-scale deflection current = 2.0 mA = 0.002 ACalculating G:G = 10.0 A / 0.002 A = 5000Calculating the shunt resistance (Rs):Rs = (5000 - 1) * 50.0 ΩRs = 4999 * 50.0 ΩRs = 249,950 Ω = 0.01 Ω (rounded to two decimal places)Therefore, the shunt resistance that must be connected across the galvanometer is approximately 0.01 Ω.
