🔍 Key Concepts

• Use Ohm's Law to relate voltage, current, and resistance in a DC circuit. • Figure A is a simple series DC circuit with a resistor, so ignore inductance and capacitance from the other figures. • Be careful with unit consistency and dividing correctly when using the resistance value of 1.74 ohms.

💭 Think About

• What basic formula links volts, ohms, and amps in a purely resistive DC circuit like figure A? • If you solve that formula for current, how do you substitute 115 V and 1.74 ohms, and what is the numerical result? • After you compute the current, which multiple-choice option is closest to your calculated value?

✅ Before You Answer

• Confirm you are using DC Ohm's Law: V = I × R and not any AC impedance formulas. • Double-check the division step when calculating I from V and R. • Compare your final current value with each option and verify that the order of magnitude (fractions of an amp vs tens of amps) makes sense for 115 V across 1.74 ohms.
