In the figure R1 214 Ohm R2 526 Ohm and the battery is ide

In the figure R_1 = 2.14 Ohm, R_2 = 5.26 Ohm, and the battery is ideal. What value of R_3 maximizes the dissipation rate in resistance 3? Number units the tolerance is +/-2%

Solution

Here ,

R1 = 2.14 Ohm

R2 = 5.26 Ohm

for the maximum power dissipation rate in resistance R3

we will use thevenin resistance

R3 = R1 || R2

R3 = 2.14 * 5.26/(2.14 + 5.26)

R3 = 1.52 Ohm

the resistance R3 for maximum power dissipation is 1.52 Ohm
