In the circuit in the figure below, the batteries have negligible internal resistance. $($Take $R_1=2\mathrm{.}65,R_2=3\mathrm{.}65,$ and $R_3=6\mathrm{.}90.)$

$$

$($a$)$ Find the magnitude of the current in each resistor.

$I_{2\mathrm{.}65}=A$

$I_{3\mathrm{.}65}=A$

$I_{6\mathrm{.}90}=A$

$($b$)$ Find the magnitude of the potential difference between points a and $b.$

$$

$($c$)$ Find the power supplied by each battery.
