5 Questions
What is the definition of electric current?
Electric current is defined as the rate of flow of positive charge carriers.
What are the units for measuring electric current?
Electric current is measured in units of amperes (A) or amps.
What is the symbol for current?
The symbol for current is $I$.
What is the equation that relates charge, current, and time?
The equation that relates charge ($\Delta Q$), current ($I$), and time ($\Delta t$) is $I = \frac{\Delta Q}{\Delta t}$.
What happens when two oppositely charged conductors are connected together?
When two oppositely charged conductors are connected together, charge will flow between the two conductors, causing a current.
