The emf \( \varepsilon \) and the internal resistance \( r \) of the battery shown in figure are \( 4.3 \mathrm{~V} \) and \( 1.0 \Omega \) respectively. The external resistance \( \mathrm{R} \) is \( 50 \Omega \). The resistances of the ammeter and voltmeter are \( 2.0 \Omega \) and \( 200 \Omega \) respectively.https://bit.ly/YTAI_PWAP https://www.pw.live
