Q

If the voltage supplied to the lighting circuit is 110 volts, how much current is drawn by a 100 watt light bulb?

🔍 Key Concepts

• Power formula for DC circuits: P = V × I, where P is power in watts, V is voltage in volts, and I is current in amps • Solving for current (I) when power and voltage are known • Checking that the final current value is reasonable for a common light bulb

💭 Think About

• Which formula directly links power (watts), voltage (volts), and current (amps)? • If P = V × I, how do you rearrange this formula to solve for I when you know P and V? • After you calculate the current, which choice is closest to your calculated value?

✅ Before You Answer

• Be sure to convert units correctly (here, watts, volts, and amps are already in base units, so no prefixes like kilo or milli are involved) • Double-check your algebra when rearranging the formula to solve for current (I) • After computing I, compare it to each answer choice and see which one matches your numerical result most closely
