🔍 Key Concepts

• Ohm’s Law and the relationship between voltage, current, and resistance: ( I = \frac{V}{R} ) • How to scale resistance when you are given ohms per 1000 feet but only use 200 feet of wire • Making sure units match: converting 200 feet into a fraction of 1000 feet before calculating total resistance

💭 Think About

• First, figure out the total resistance of 200 feet of wire using the given resistance per 1000 feet. How do you scale 4.26 ohms for a shorter length? • Once you have the total resistance, apply Ohm’s Law with the 12-volt battery. How does current change when resistance is less than 1 ohm? • Compare your computed current with the choices. Which one is closest to your calculated value?

✅ Before You Answer

• Calculate the fraction of 1000 feet that 200 feet represents and multiply the resistance per 1000 feet by that fraction • Double-check that your resistance value is reasonable (it should be less than 4.26 ohms because the wire is shorter than 1000 feet) • After using ( I = \frac{V}{R} ), confirm your units (volts, ohms, amps) and ensure your current value is within a realistic range for a low-resistance DC circuit
