🔍 Key Concepts

• Series circuit in figure A (one path for current through R1 and R2) • Use Ohm’s Law: ( R = \frac{V}{I} ) to find total circuit resistance from the source voltage and circuit current • In a series circuit, the same current flows through every component, so current through R1 = current through R2 = circuit current

💭 Think About

• From the given 32 VDC source and the current through R2, what is the total resistance of the circuit? • Once you know the total resistance, how can you use the known value of R1 to find the unknown resistance across R2? • Does the fuse and closed switch add any resistance you need to calculate for this exam-style problem?

✅ Before You Answer

• Confirm that in figure A, R1 and R2 are in series, not parallel • Convert milliampere current to amperes before using Ohm’s Law • After computing the resistance of R2, compare it with the closest matching choice in the answers provided
