Q

Two 10 W, 500 ohm resistors in parallel will dissipate how many watts?

🔍 Key Concepts

• Power rating of a resistor and what it actually limits • How parallel circuits share voltage and current • Relationship between resistance, current, and power (P = V×I, P = I²R, P = V²/R)

💭 Think About

• If each resistor is rated at 10 W, what does that tell you about the maximum power per resistor? • In a parallel circuit, what is the same across all branches, and what is shared? How does that affect total power? • If each resistor can safely dissipate 10 W, what is the combined safe power when they are used together in parallel?

✅ Before You Answer

• Be clear whether you are calculating total power rating (safe limit) or actual power used at a given voltage/current • Remember that in parallel, voltage across each resistor is the same • Check that your final answer does not exceed the sum of the individual power ratings of both resistors
