An electric field is the physical field that surrounds electrically charged particles. Charged particles exert attractive forces on each other when their charges are opposite, and repulse each other when their charges are the same. Because these forces are exerted mutually, two charges must be present for the forces to take place. The electric field of a single charge describes their capacity to exert such forces on another charged object. These forces are described by Coulomb's law, which says that the greater the magnitude of the charges, the greater the force, and the greater the distance between them, the weaker the force. Thus, we may informally say that the greater the charge of an object, the stronger its electric field. Similarly, an electric field is stronger nearer charged objects and weaker further away. Electric fields originate from electric charges and time-varying electric currents. Electric fields and magnetic fields are both manifestations of the electromagnetic field, Electromagnetism is one of the four fundamental interactions of nature.

यदि किसी स्थान पर स्थित किसी स्थिर आवेशित कण पर बल लगता है तो कहते हैं कि उस स्थान पर विद्युत्-क्षेत्र है। विद्युत क्षेत्र आवेशित कणों के द्वारा उत्पन्न होता है या समय के साथ परिवर्तित हो रहे चुम्बकीय क्षेत्र के कारण। विद्युत क्षेत्र की अवधारणा सबसे पहले माइकल फैराडे ने दिया था। विद्युत क्षेत्र एक सदिश (vector) राशि है।
