🔍 Key Concepts

• Use Ohm's Law for a simple DC resistive circuit: ( I = \frac{E}{R} ). • In figure A, the only load is a resistor R; ignore the inductor and capacitor shown in B and C. • Be careful with units and decimal placement when dividing voltage by resistance.

💭 Think About

• Which basic DC formula directly relates voltage, current, and resistance, and how can you rearrange it to solve for current? • If you divide 442.7 volts by 1.25 ohms, what approximate current do you get, and which choice is closest to that value? • Looking at the answer choices, which ones are clearly too small or too large for a 400+ volt source feeding just 1.25 ohms of resistance?

✅ Before You Answer

• Confirm you are using figure A (resistive circuit), not B or C. • Verify you used R = 1.25 Ω and E = 442.7 VDC exactly as stated. • After calculating, check that your current is in hundreds of amps, not tens, based on the size of the voltage and resistance.
