ELECTRICITY AND MAGNETISM
Hello guys I'm Swift (Science Lair) it has been long since I posted anything, but today i would be taking you through the aspects of electricity and magnetism
Lets start with the definition of an electric field
Electric Field is a region where a small positive charge experiences a force.
Electric Current is the rate of flow of charge.
EMF (electromotive force) is the work done by a cell when a unit positive charge to move rounds the circuit.
PD (potential difference) is the energy converted from electrical form to non electrical (heat) form when a unit positive charge moves between two points.
Voltage = Current × Resistance = IR
