Charge

Question 1

What is Electrical Charge?

Answer 1

A physical property that causes matter to experience a force within an electromagnetic field

Question 2

What is the symbol and unit for charge?

Answer 2

Symbol: Q
Unit: Coulombs, C

Question 3

What is the formula for charge?

Answer 3

Charge (Q) = Current (I) x Time (t)

Question 4

What is Elementary charge?

Answer 4

Is the electric charge carried by a single proton or electron.

Question 5

What is the symbol for elementary charge?

Answer 5

e (or qe)

Question 6

What is the symbol for the number of elementary charges?

Answer 6

n

Question 7

What is the formula for the number of elementary charges?

Answer 7

n = Q/e

Question 8

What is the law of the Conservation of Charge?

Answer 8

A law that states that charge must be conserved - the charge that is lost by one object is gained by another.

Question 9

What is Coulombs Law?

Answer 9

States that:

• Like charges repel
• Opposite charges attract
• Force proportional to the product of the charges
• Inversely proportional to the square the the distance between them.

Question 10

What is the formula for the magnitude of the force between charged objects?

Answer 10

Force = k x Q1Q2/r^2

k = 9 x 10^9 (constant)

Question 11

Answer 11

micro coulomb x 10^-6 = coulomb

Question 12
