Question 1 of 27070

Q

The total power dissipation capability of two 10 watt, 500 ohm resistors connected in series is:

🔍 Key Concepts

• Power rating of a resistor vs the power actually dissipated • How series connections affect voltage, current, and total resistance • Formula for electrical power: P = I^2 R, P = V^2 / R, or P = V × I

💭 Think About

• If each resistor is rated at 10 watts, what is the maximum power each one can safely handle? • In a series circuit, the same current flows through each resistor. How does that affect how much power each resistor can dissipate? • What is the total maximum safe power for the pair if neither resistor is allowed to exceed its 10 watt rating?

✅ Before You Answer

• Be clear on the difference between resistor rating (maximum safe power) and actual operating power in a given circuit. • Confirm that in series, the current is the same through both resistors, but each may have a different voltage drop if resistances differ. • Check whether simply adding wattage ratings is appropriate when two identical resistors share the same current in series.
