Simple circuit

Definition

A simple circuit consists of a power source, a conductive path, and a load. It allows electric current to flow through a closed loop.

5 Must Know Facts For Your Next Test

1. A simple circuit typically includes elements such as batteries, resistors, and wires.
2. Ohm's Law ($V = IR$) is fundamental in analyzing the behavior of simple circuits.
3. The total resistance in a series circuit is the sum of the individual resistances.
4. In a parallel circuit, the voltage across each component is the same.
5. The Kirchhoff's Voltage Law states that the sum of all voltages around a closed loop equals zero.

Ohm's Law: A principle stating that the current through a conductor between two points is directly proportional to the voltage across the two points, represented by $V = IR$.

Series Circuit: A circuit in which components are connected end-to-end so that current flows through each component sequentially.

Parallel Circuit: A circuit where components are connected across common points or junctions, providing multiple paths for current.
