Electricty

Question 1

Electrical conductors

Answer 1

object that can conduct electricity

Question 2

Electric field strength

Answer 2

E= F/Q force per unit charge on a positive test charge at that point

Question 3

Electric Potential

Answer 3

Work done per unit charge to move a positive test charge from infinity to the point

Question 4

Electric field strength between two plates

Answer 4

E=V/d

Question 5

Coulomb’s law of force

Answer 5

1/4piE * Qq/r^2 forces between two test charges id proportional to the product of test charges and inversely proportional to r^2

Question 6

Electric field strength

Answer 6

1/4piE * Q/r^2

Question 7

Electric Potential

Answer 7

Q/4piEr

Question 8

Field lines go in which direction

Answer 8

from positive to negative (positive test charge, the line go outwards

Question 9

electric potential characteristics

Answer 9

Dependent on electric charge and distance from source

greatest at end of the plate with the same charge

Question 10

Electric potential energy characteristics

Answer 10

greatest when work is being done

object moving in the opposite direction to the force
