Read each question carefully and provide your answer in the space provided. Show all your work for calculations.
1. Which of the following statements is true about a series circuit?
Current is divided among components.
Voltage is the same across all components.
Total resistance is the sum of individual resistances.
If one component fails, others continue to operate.
2. According to Ohm's Law, if the voltage across a resistor is doubled, what happens to the current, assuming resistance remains constant?
The current is halved.
The current remains the same.
The current is doubled.
The current is quadrupled.
