Circuits: Series, Parallel, and Power — Homework
Decide whether each part of the circuit is wired in series or in parallel before combining resistances.
- 1.Two resistors, 4 ohm and 6 ohm, are connected in series with a 30 V battery. Find the equivalent resistance, the current, and the voltage across each resistor.
- 2.Two equal 10 ohm resistors are connected in parallel. Find the equivalent resistance.
- 3.For the series circuit in the first problem, find the power dissipated by the 6 ohm resistor.
- 4.Explain why one burnt-out bulb in an old-style series string of holiday lights would darken the entire string, while a modern parallel-wired string does not have this problem.
- 5.Describe a real household circuit (a power strip, a string of lights, an extension cord with multiple devices) and explain whether its devices are effectively wired in series or in parallel, and why that matters.
