A
Total power is the sum of the powers consumed by each load (resistor) divided by the number of loads
B
Total power is never more than the power consumed by the largest load
C
Total power is always less than the power consumed by the smallest load
D
Total power is the sum of the powers consumed by each load

🔍 Key Concepts

• Power in a DC circuit (P = V × I, or P = I² × R, or P = V² ÷ R) • How current and voltage behave in a series circuit • Difference between individual load power and total circuit power

💭 Think About

• If you know the current through each resistor is the same in series, how does that affect the power each one uses? • How would you calculate the total power taken from the source: by looking at the source voltage and total current, or by looking at each resistor separately? • Think about energy: does each resistor use some of the source’s power, and what happens if you add them all together?

✅ Before You Answer

• Be clear on how current is the same through all components in a series circuit • Remember that each load (resistor) has its own voltage drop and therefore its own power consumption • Check which choice correctly matches the idea that total power relates to the sum of all individual power consumptions in the circuit
