# A 5V battery with internal resistance $2\Omega$ and a 2V battery with internal resistance $1\Omega$ are connected to a $10 \Omega$ resistor as shown in the figure. The current in the $10\Omega$ resistor is

$\begin {array} {1 1} (A)\;0.27\: A\: P_2 \: to \: P_1 & \quad (B)\;0.03\: A\: P_1 \: to \: P_2 \\ (C)\;0.03\: A\: P_2 \: to \: P_1 & \quad (D)\;0.27\: A\: P_1 \: to \: P_2 \end {array}$

Can you answer this question?

$V_{p_2}-V_{p_1} = \large\frac{\large\frac{5}{2}+\large\frac{0}{10}-\large\frac{2}{1}}{\large\frac{1}{2}+\large\frac{1}{10}+\large\frac{1}{1}}$
$I = \large\frac{V_{p_2}-V_{p_1}}{10}$ $0.03$ from $p_2 \rightarrow p_1$
