In a parallel circuit , there are points at which the current can branch or split up into different paths. The flow divides and later rejoins. The total cross-sectional area the current (or water) flows through is increased , therefore decreasing the resistance to flow: 1 R parallel 1 R 1 1 R 2 1 R 3
