An element with emf \( \varepsilon \) and internal resistance \( r \) is connected across an external resistance \( R \). The maximum power in external circuit is \( 9 \mathrm{~W} \). The current flowing through the circuit in these conditions is \( 3 \mathrm{~A} \). Then which of the following is/are correct?https://bit.ly/YTAI_PWAP https://www.pw.live
