This blog contains the lesson tackle in our Circuits 1 with covers up to the finals topics ..but it is upated weekly by which it is one by one review the lesson the topics that our professor has tackled to us .. 

Chapter 1 :

what is a circuit ?

A lot of appliances and gadget are widely are expanding and most of it usually are in our house in all in our environment which serves us part of our daily life. And through that appliances and gadget we have .. i have learned most of it is applied by the circuits.

A circuit contains a power supply which provides electricity in a circuit and the electricity that flows in a circuit is called current. when the power supply gets electricity ,the current that flows through a socket in an alternating current, and is converted through direct current in which the electricity that flow in an electrical device by the use of power supply ..

Charge- A form of charge, designated positive, negative, or zero found on the elementary particles that make up all known matter. Particles with electric charge interact with each other through the electromagnetic force creating electric fields, and when they are in motion, magnetic fields

Current - An electric current is a flow of electric charge. Electric charge flows when there is voltage present across a conductor.

Voltage - is a representation of the electric potential energy per unit charge. Voltage is a scalar quantity. The SI unit of voltage is the volt, such that 1 volt = 1 joule/coulomb.

Power - electric power is the rate at which electric energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second.

CIRCUIT ELEMENT 

An element is the building block of a circuit and Electric circuit s the interconnecting of the elements.

Types of Elements

*Active Elements - capable of generating energy which has a negative power 

*Positive Energy - which absorbs energy example of it are resistors, capacitor, inductors.

Types of Sources 

independent source - does not depend to other element to supply Voltage or current.

Dependent source - does depend on the other element of the circuit.
