Static electricity and Potential Difference and capacitance
Cards in this deck (9)
- 1InsulatorAny substance which electric charge cannot flow
- 2ConductorAny substance through which electric charge can flow
- 3Coulomb's Lawstates that the force of attraction or repulsion between two point charges is directly proportional to the product of the charges and inversely proportional to square of the distance between them
- 4Electric Fieldis any region of space where a static electric charge experiences a force other than the force of gravity
- 5Electric Field strengththe electric field strength E at a point in an electric field is the force per unit charge at that point. i.e. electric field strength is the force per coulomb
- 6Potential Differencethe potential difference between two points in an electric field is the work done in bringing a charge of +1 C from one point to the other
- 7The VoltThe potential difference between two points is 1 volt if 1 joule of work is done when 1 coulomb is brought from one point to the other
- 8The CapacitanceThe Capacitance of a conductor is the ratio of the charge on the conductor to its potential
- 9The FaradA conductor has a capacitance of 1 Farad if placing a charge of 1 C on it raises its potential by 1 volt
