Physics 2 M5

Electric Circuit

→ is a combination of one or more networks which may be a combination of one or more network which gives closed path to the electric current.

Nodes/Junction

→ Is any point on a circuit where the terminal of two or more circuit elements meet.

Branch

→any sequence of element connected between nodes that starts and ends at the a nodes. It represents a series circuit which has the same current.

Loop

→ Any closed path in a circuit

Kirchhoff’s Circuit Laws

allow us to solve complex circuit problems by defining a set of basic network laws and theorems for the voltages and currents around a circuit

Kirchhoff’s Circuit Laws

are two equalities that deal with the current and potential difference (voltage) in the lumped element model of electrical circuits.

Gustav Kirchhoff

First describe in 1845 by German Physicist ______. This generalized the work of Georg Ohm and preceded the work of James Clerk Maxwell.

KCL

“The total current or charge entering a junction or node is exactly equal to the charge leaving the node as it has no other place to go except to leave, as no charge is lost within the node.”

KVL

“In any closed loop network, the total voltage around the loop is equal to the sum of all voltage drops within the same loop.”
