🔍 Key Concepts

• RMS (Root Mean Square) current and what 'effective value' means in AC/RF circuits • How heating (power dissipation) in a resistor depends on current (P = I²R) • Difference between peak, average, and RMS current values

💭 Think About

• Ask yourself: When we say 'effective value' of an AC or RF current, what DC current would produce the same heating effect in a resistor? • How does squaring the current in the power formula P = I²R relate to how we define RMS (effective) current? • If two currents produce the same heating, how must their numerical values compare when one is already defined using the RMS concept?

✅ Before You Answer

• Be clear on the definition: RMS (effective) current is the value that produces the same heating effect as a DC current of the same magnitude. • Verify that power (heating) depends on I², not just I, so think about whether a factor of 2 makes sense in that context. • Double-check the difference between peak current and RMS/effective current so you don’t mix those up with the heating relationship.
