Q

What is the maximum rated current-carrying capacity of a resistor marked “2000 ohms, 200 watts”?

🔍 Key Concepts

• Ohm’s Law relationship between voltage, current, and resistance • How power (watts) relates to voltage, current, and resistance • How to solve for current when you know resistance and power rating

💭 Think About

• Which formula links power, current, and resistance directly, without needing voltage first? • Once you have that formula, how can you rearrange it to solve for current? • After finding the current, which answer choice matches your calculated value, including correct placement of the decimal point?

✅ Before You Answer

• Write and use the correct formula: P = I² × R or P = V × I and V = I × R • Carefully check your algebra when solving for I (current) from P = I² × R • Double-check your calculator work and confirm that the result is reasonable for a 200‑watt resistor (very large currents would usually mean much higher power than 200 W).
