Questions & Step-by-Step Solutions
In a series circuit, if one resistor fails open, what happens to the current?
Step 1: Understand what a series circuit is. In a series circuit, all components are connected one after another in a single path.
Step 2: Know what a resistor does. A resistor limits the flow of electric current in the circuit.
Step 3: Recognize what it means for a resistor to fail open. If a resistor fails open, it means it stops conducting electricity completely.
Step 4: Realize the effect of an open resistor in a series circuit. Since all components are in a single path, if one component (like a resistor) fails open, it breaks the path.
Step 5: Conclude what happens to the current. When the path is broken, no current can flow through the circuit, so the current becomes zero.
