Current And Charge Equations

Question 1

What is the formula for electric current?

Answer 1

I = Q / t, where I is current, Q is charge, and t is time.

Question 2

True or False: Current is measured in coulombs.

Answer 2

False. Current is measured in amperes.

Question 3

Question 6

If 5 coulombs of charge pass through a conductor in 2 seconds, what is the current?

Answer 6

2.5 A

Question 7

True or False: Charge can be created or destroyed.

Answer 7

False. Charge cannot be created or destroyed.

Question 8

What is the relationship between charge, current, and time?

Answer 8

Charge is the product of current and time: Q = I * t.

Question 9

Multiple Choice: Which equation correctly describes the relationship between current, charge, and time?

Answer 9

A) Q = I * t B) I = Q + t C) I = Q / t D) A and C
