Q5: Three -Ω resistors are connected as shown in Fig- ure P28.5. The maximum power that can safely be delivered to any one resistor is W.
(a) What is the maximum potential difference that can be applied to the terminals a and b?
(b) For the voltage determined in part (a), what is the power delivered to each resistor?
(c) What is the total power delivered to the combina- tion of resistors?
r2 = Ω
r3 =Ω
