ବୈଦୁତିକ କ୍ଷେତ୍ର

Electric field lines emanating from a point positive electric charge suspended over an infinite sheet of conducting material.

ବୈଦୁତିକ କ୍ଷେତ୍ର ହେଉଛି ବିଦ୍ୟୁତ୍-ଚୁମ୍ବକୀୟ କ୍ଷେତ୍ରର ଏକ ଅଂଶ ବିଶେଷ । ଏହା ଏକ vector field ଅଟେ ଏବଂ ମାକ୍ସୱେଲଙ୍କ ସମୀକରଣର ବର୍ଣ୍ଣନା ଅନୁସାରେ ଏହା ବୈଦୁତିକ ଚାର୍ଜ କିମ୍ବା time-varying ଚୁମ୍ବକୀୟ କ୍ଷେତ୍ରଦ୍ୱାରା ସୃଷ୍ଟି ହୋଇଥାଏ । ବୈଦୁତିକ କ୍ଷେତ୍ର ସମ୍ପର୍କରେ ଧାରଣା ସର୍ବପ୍ରଥମେ ମାଇକେଲ ଫରାଡ଼େ ଦେଇଥିଲେ ।

ସଂଜ୍ଞା

The electric field $𝐄$ at a given point is defined as the (vectorial) force $𝐅$ that would be exerted on a stationary test particle of unit charge by electromagnetic forces (i.e. the Lorentz force). A particle of charge $q$ would be subject to a force $𝐅=q\cdot 𝐄$.

Its SI units are newtons per coulomb (N⋅C⁻¹) or, equivalently, volts per metre (V⋅m⁻¹), which in terms of SI base units are kg⋅m⋅s⁻³⋅A⁻¹.
