Problem4. Resistors are given a power rating. For example, resistors are available with ratings of 1/8 W, 1/4 W, 1/2 W, and 1 W. A 1/2-W resistor is able to safely dissipate 1/2 W of power, indefinitely. Resistors with larger power ratings are more expensive and bulkier than resistors with lower power ratings. Good engineering practice requires that resistor power ratings be specified to be as large as, but not larger than, necessary. The value of the current source current is i, = 30 mA R₁ Consider the circuit shown in Figure to the right. The values of the resistances are R₁ =100022, R₂ = 20002, and R₂ = 40002 Specify the power rating for each resistor. R3 R2 wwwwwwww i, = is
