Q

The current through two resistors in series is 3 A. Resistance #1 is 50 ohms, resistance #2 drops 50 V across its terminals. What is the total voltage?

🔍 Key Concepts

• Ohm’s Law (V = I × R) and how voltage, current, and resistance relate • Behavior of series circuits: the same current flows through all components • How to find individual voltage drops and then combine them to get total voltage

💭 Think About

• First, use the given current and the resistance of #1 to find the voltage drop across resistor #1. What formula connects these three? • You already know the voltage drop across resistor #2. Once you have both voltage drops, how do you get the total supply voltage in a series circuit? • Check that the same current (3 A) is being used consistently for the resistor where only resistance is given.

✅ Before You Answer

• Be sure to apply V = I × R correctly with the right values and units (amps, ohms, volts). • Confirm that total voltage in series equals the sum of the individual voltage drops. • Verify that the current is the same through both resistors because they are in series.
