Problem G. 771. (February 2022)
G. 771. In the connection shown in the figure, the resistors have the same resistance \(\displaystyle R\), and at a voltage \(\displaystyle U\) the their power is \(\displaystyle P\).
What is the power dissipated in each resistor with the switches open (O) or closed (C)? Fill in the table!
