Series Circuit

In a Series circuit we have components connected in a long chain from terminal of the power source to the other. And the current will flow in 1 direction only.

Parallel Circuit

All the components are connected across each others forming more than 1 electrically common points. A path for electric currents formed by one of the load components (resistor bulb, LED) is called a branch.

OHMS LAW

Is the definition of the relationships between voltage, current, resistance and power. The resistance value through which one volt will remain a current of one amp, is one ohm.

Kirchhoff's Law

At any junction (point) in a electrical circuit, the sum of the current flowing into that point is the same to the total current flowing out of the point (Current Law).

The directed sum of the boltage around any closed circuit is zero (Voltage Law)

  • Total current in a parallel circuit is equal to the sum of the individual branch currents.
  • Total resistance in a parallel circuit is less than any of the individual resistances
  • Components in a parallel circuit have the same voltage.
