There are n identical resistors in a section of a circuit. The potential difference across this section of the circuit is ΔV. The resistors can be placed either all in series, or all in parallel. (a) Which configuration "consumes" more power, series or parallel? (b) By what factor must you multiply the power consumed by the low-power configuration to get the power consumed by the higher-power configuration (1/n, 1/n^2, n, or n^2)?
