Question 1 of 10
What is the SI unit of electric charge?
The SI unit for electric charge is the Coulomb (C).
Question 2 of 10
What is the formula that relates charge (Q), current (I), and time (t)?
Charge is equal to the current multiplied by the time (Q = It).
Question 3 of 10
Which of the following best describes electric current?
Electric current is defined as the rate of flow of charge.
Question 4 of 10
What is the charge of a single electron?
A single electron has a charge of -1.602 x 10^-19 Coulombs.
Question 5 of 10
What type of electric current changes direction and magnitude periodically?
AC current is characterized by a changing direction and magnitude.
Question 6 of 10
What is the symbol used to represent electric current?
Electric current is represented by the symbol 'I'.
Question 7 of 10
According to Coulomb's law, the force between two charged particles is ______ proportional to the square of the distance between them.
Coulomb's law states that force is inversely proportional to the square of the distance.
Question 8 of 10
What represents the deficiency of electrons on the body?
A deficiency of electrons results in a positive charge.
Question 9 of 10
What is the unit of measurement for current?
The unit of measurement for current is the Ampere.
Question 10 of 10
If the current through a wire is 2 Amperes, how much charge passes a point in the wire in 5 seconds?
Using Q = It, Charge = 2 A * 5 s = 10 Coulombs.
