A series parallel circuit has three resistors: one uses 2 w, the second 3 w and the third 1.5 w. how much current does the circuit require from a 12-v battery?

. A battery of many cells or a single cell can maintain potential difference.

W=v2/r so v2/w =r that's why the r of each appliance is 72, 48, and 96 respectively.... They are in parallel so 1/ total resistance is sum of their reciprocal = 1/72+1/48+1/96... After calculating this resistance use v=ir to find current... Mark my abs as brainliest if it helped
