357226 A non-ideal ammeter and voltmeter are connected in series with an ideal cell of emf \({E=22 {~V}}\) as shown in figure. Reading of the voltmeter is \({V_{0}}\). When a resistance is added in parallel to the voltmeter its reading becomes \({\dfrac{V_{0}}{10}}\) and the reading of the ammeter becomes 10 times the earlier value. Find the value of \({V_{0}}\)
