🔍 Key Concepts

• Maximum power transfer theorem from basic electrical theory • Relationship between source (internal) impedance and load impedance • What happens to current and voltage across the load as the load impedance changes

💭 Think About

• If the load impedance is made very large compared to the source impedance, what happens to the current and the power delivered to the load? • If the load impedance is made very small compared to the source impedance, what happens to the voltage across the load and the power delivered? • At what relationship between source and load impedance do we get the best balance of current and voltage at the load so that the product (power) is maximized?

✅ Before You Answer

• Think about the mathematical expression for power in the load in terms of voltage, current, and impedance (P = V × I, and Ohm’s Law). • Consider the special condition used in impedance matching for antennas, audio systems, and transmission lines to get maximum power into the load. • Verify whether the condition involves the load impedance being equal to, greater than, or less than the source’s internal impedance.
