**Electric current, voltage, resistance, conductance, energy**

**Electric current**:- it is a flow of electrons in a circuit. Electric

current messured by ammeter and it denoted as capital “I”.

SI unit :- Ampere

**Voltage**:- it is the potential difference between the two terminal. Voltage is also known as electric pressure or electric tension. Voltage is messured by voltmeter and denoted by capital “V”.

SI unit :- Voltage

**Energy :-**it is the capacity for doing work, it may be various form nuclear, electrical, chemical, thermal

etc. it is the process of transfer from one body to another.
It is denoted by “E”.

SI unit :- joule

**Power :-**it is the ability to doing work. Power is also define as the amount of energy transferred per unit

time. It is
denoted by “P”.

Power
= work/time

SI unit :-
watt(W)

**Resistance :- i**t is measure of the opposition to flow of current in the electrical circuit. It is denoted by “R”.

SI unit : -
ohm (Î©)

**Conductance**:- it is the property in which an object conducts electricity. It is denoted by “G”.

Unit :-
Siemens

**Capacitance:-**It is the property of an object to store an electric charge. It is denoted by capital “C”.

SI unit : - Farad

**Inductance :**- it is the property that opposes the change of current flowing through it. It is denoted by capital “L”.

SI unit :- henry (H)
