In a parallel circuit, the voltage across each branch is

  1. divided in proportion to the resistances
  2. zero
  3. the same as the source voltage
  4. the sum of the branch currents

Answer

C. the same as the source voltage

Solution

All branches of a parallel circuit are connected across the same two nodes, so each has the full source voltage across it.
