Problem 1: Verify Power Dissipation
Circuit
Vs = 10 V, R1 = 15 kΩ, R2 = 10 kΩV
Step 1: Calculate Total Resistance
Since R1 and R2 are in series, the total resistance Rt is:
RT = R1 + R2 = 15 kΩ + 10 kΩ = 25 kΩR_
Step 2: Calculate Total Current
Using Ohm's Law: I = Vs / Rt = 10 V /2 5 kΩ
=0.4 mA
Step 3: Calculate the Power Supplied by the Source
Ps = Vs × I = 10 V × 0.4 mA = 4 mW
Step 4: Calculate Power Dissipated by Resistors
PR1 = I2 × R1= (0.4 mA) 2× 15 kΩ=2.4 mW
PR2= I2 × R2 = (0.4 mA) 2 × 10 kΩ=1.6 mWP
Ptotal= PR1 + PR2 = 2.4 mW + 1.6 mW = 4 mWP
Thus, the “total power”...
