Solution

Since

P_max=V₁²/R₁

=>25.5 =V₁²/100

V₁=50.5 Volts

Current flowing in the circuit

I=V₁/R₁=50.5/100 =0.505 A

equivalent resistance of parallel combination

R_p =(1/100 + 1/100)^-1=50 ohms

So Voltage drop across them

V_p=I*R_p=0.505*50 =25.25 Volts

So Power delivered to resistors is

P_left=25.5 W

P_top=P_bottom=(I/2)*25.25 =(0.505/2)*25.25 =6.3 Watts
