How much power is dissipated by each resistor in FIGURE EX28.8?

Short Answer

Expert verified

P1=1.92WandP2=2.88W

Step by step solution

01

Given information

We need to find the power dissipation by each resistor.

02

simplify

Let us consider the current flowing be 'i':

Then,

鈬�i=鈭�R1+R2i=12V(12+18)惟I=1230Ai=0.4A

The power dissipated in R1:

P1=i2R1P1=(0.4A)2脳12惟 P1=0.16A脳12惟P1=1.92W

The power dissipated in R2:

P2=i2R2P2=(0.4A)2脳18惟 P2=16A脳18惟P2=2.88W
