Electricity

Question 1

EMF

Answer 1

energy per unit charge converted from other forms of energy into electrical energy from the supply

Question 2

terminal p.d.

Answer 2

energy per unit charge available at the terminal of the supply for conversion of electrical energy into other types of energy

Question 3

Kirchoff’s first law

Answer 3

current that flows into any junction = current that flows out of the junction

Question 4

Kirchoff’s second law

Answer 4

the sum of EMFs around any closed loop = sum of potential differences across any components

Question 5

definition for electric current

Answer 5

rate of flow of charge

Question 6

Kirchoff’s first Law is the consequence of the conservation of…

Answer 6

charge (junction can’t create/store charge = I*t)

Question 7

Kirchoff’s second Law is the consequence of the conservation of…

Answer 7

energy (each charge carrier can only take one loop round circuit. gains energy passing through cells, loses passing through components, sum must be zero)
