New Curriculum Physics Note of Current Electricity

March 19, 2026June 20, 2014 by Shah Jamal

Electric current is the rate of charge flow past a given point in an electric circuit, measured in Coulombs/second which is named Amperes. In most DC electric circuits, it can be assumed that the resistance to current flow is a constant so that the current in the circuit is related to voltage and resistance by … Read more

Static electricity

March 19, 2026May 24, 2014 by Shah Jamal

Static electricity is an excess of electric charge trapped on the surface of an object. The charge remains until it is allowed to escape to an object with a weaker or opposite electrical charge, such as the ground, by means of an electric current or electrical discharge. Static electricity is named in contrast with current … Read more
