Question

Part A) Find the value of the variable resistor Ro in the circuit that will result in maximum power dissipation in the 6 ? resistor (Figure 1) if v = 42V . (Hint: Hasty conclusions could be hazardous to your career.)

Part B) What is the maximum power that can be delivered to the 6? resistor

Part A) Find the value of the variable resistor Ro in the circuit that will result in maximum power dissipation in the 6 ? resistor (Figure 1) if v = 42V . (Hint: Hasty conclusions could be hazardous to your career.) Part B) What is the maximum power that can be delivered to the 6? resistor

Explanation / Answer

if Ro=0 ohm then no power loss and all power will be transfered to the load.

so Ro=0 ohm for maximum power condition.dont apply maximum power transfer theorom here.because load is constant here.

maximum power=V^2/R=42^2/6=294 watts
