What is the formula for current (i) in terms of charge (q) with respect to time (t)?
What is the formula for current (i) in terms of charge (q) with respect to time (t)?
The formula for current (i) in terms of charge (q) with respect to time (t) is given by $i(t) = \rac{dq(t)},{dt}$.
If the charge is described by the function $q(t) = t^3 - 2t + 7$ coulombs, what is the current (i) as a function of time (t)?
If the charge is described by the function $q(t) = t^3 - 2t + 7$ coulombs, what is the current (i) as a function of time (t)?
If the charge is described by the function $q(t) = t^3 - 2t + 7$ coulombs, then the current (i) as a function of time (t) is given by $i(t) = \rac{dq(t)},{dt} = 3t^2 - 2$ A.
Explain the relationship between current direction and the direction of positive charge flow.
Explain the relationship between current direction and the direction of positive charge flow.
The current direction always follows the direction of positive charge flow. However, since electrons are negatively charged particles, they flow in the opposite direction, which is why current direction is in the direction opposite of negative charge flow.
