Practice question · Select all that apply
Select every statement that is TRUE of resistors in circuits.
Hints
- Test the parallel claim on the 6 and 3 ohm pair you already combined.
- One option reverses the direction of a rule.
Show the answer
- A. In series the resistances add
- B. Components in parallel have the same voltage across them
- C. Components in series carry the same current
- E. Power dissipated in a resistor is the current squared times the resistance
Why
The 6 and 3 ohm pair combined to 2 ohms, smaller than both, so option three is false. The rest are exactly as taught: series shares current and adds resistance, parallel shares voltage, and power grows with the square of the current.
