Three batteries and four resistors are connected as shown above. Find (a) the current in each resistor,
(b)
the power supplied by each battery, and
(c) the power dissipated in each resistor.

how to calculate all of these?

Hi trans_pie! :smile:

Let's do (a) first.

What do Kirchhoff's rules give you for the currents in each of the two circuits? :smile:
