Why is light considered a carrier for electromagnetic force?

By Lou | Published: January 14, 2012
Why is light considered a carrier for electromagnetic force? i am very confused with the notion that the electromagnetic force is carried by light(part of the electromagnetic spectrum), photons to be precise. I get how an electric field influences a magnetic field and vice versa, but have no clue how does light come into the picture? [...]

Why is current the same everywhere in a series circuit?

By Lou | Published: November 4, 2011
Why is current the same everywhere in a series circuit? Considering the fact that I am referring to a series circuit, I am confused with the following. If current is the rate at which electrons flow (coulombs per second) at a particular point, then wouldn’t the current be higher before a resistor and lower after the [...]
