What is flux in electric field? Electric flux, property of an electric field that may be thought of as the number of electric lines of force (or electric field lines) that intersect a given area. The negative flux just equals in magnitude the positive flux, so that the net, or total, electric flux is zero. […]

What happens to capacitors at low frequencies?
What happens to capacitors at low frequencies? At very low frequencies, such as 1Hz our 220nF capacitor has a high capacitive reactance value of approx 723.3KΩ (giving the effect of an open circuit). At very high frequencies such as 1Mhz the capacitor has a low capacitive reactance value of just 0.72Ω (giving the effect of […]

What makes a real image?
What makes a real image? A real image occurs where rays converge, whereas a virtual image occurs where rays only appear to diverge. Real images can be produced by concave mirrors and converging lenses, only if the object is placed further away from the mirror/lens than the focal point, and this real image is inverted. […]
