Q

What is the time constant of a circuit having a 220-microfarad capacitor and a 1-megohm resistor in parallel?

🔍 Key Concepts

• RC time constant formula and what it represents in a circuit • How to correctly convert microfarads (µF) and megohms (MΩ) into base SI units (farads and ohms) • Multiplying large and small numbers using powers of ten (scientific notation)

💭 Think About

• What is the basic formula for the time constant of a resistor-capacitor (RC) circuit, and which components does it involve? • If you convert 220 microfarads to farads and 1 megohm to ohms, what numerical values do you get? • After multiplying those values, what is the order of magnitude (hundreds, tens, ones, tenths) of the result in seconds?

✅ Before You Answer

• Be sure you correctly convert 220 µF into farads (F) using powers of ten. • Be sure you correctly convert 1 MΩ into ohms (Ω) using powers of ten. • After calculating, check if your answer is in seconds, and compare its size to the options to see which is closest in both value and order of magnitude.
