Rheolau Cylchedau Cyfres Series Circuit Rules

  • NID yw cerrynt yn cael ei ddefnyddio gan y cydrannau. Current is not used up by components.

  • Mewn cylched cyfres, mae'r cerrynt yr UN FATH ym mhobman yn y gylched. In a series circuit, the current is THE SAME everywhere in the circuit.

  • Mae amedr (sy'n cael ei ddefnyddio i fesur cerrynt) bob tro yn cael ei roi i mewn i'r gylched mewn cyfres â'e cydrannau. The ammeter (which is used to measure current) is always placed in the circuit, in series to the other components.

Rheolau Cerrynt Cylchedau Paralel

Parallel Circuit Current Rules

  • Mewn cylched paralel, mae'r cerrynt yn cael ei rannu ymysg y cydrannau. In a parallel circuit, the current is shared amongst the components.

  • Mae cerrynt yn mynd i mewn i gyffordd (junction) yn hafal i'r cerrynt sy'n llifo allan o'r cyffordd. the current flowing into a junction is equal to the current flowing out of a junction.
