🔍 Key Concepts

• Use Ohm's Law for DC circuits: V = I × R • In figure A, the only effective opposition to current is the resistance R (ignore the ideal switch when it is closed) • To find current, you will need to rearrange the formula to solve for I

💭 Think About

• If you know the voltage across a pure resistor and its resistance, how can you calculate the current through it? • What happens to current when you increase resistance while keeping voltage the same—does it go up or down? Use that to rule out unrealistic answers. • After computing the current, which option is closest to your calculated value?

✅ Before You Answer

• Be sure you convert and keep units consistent: volts (V), ohms (Ω), amperes (A). • Double‑check your algebra when rearranging V = I × R to solve for I. • After calculating, verify that your answer is a reasonable current for 115 V across 12 Ω (not extremely huge or tiny).
