Questions and Answers
What is the difference between AC and DC current?
AC (alternating current) changes direction periodically while DC (direct current) flows in only one direction.
What is Ohm's Law and how is it used to calculate current, voltage, and resistance in a circuit?
Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points. It can be used to calculate current (I), voltage (V), and resistance (R) in a circuit using the formula I = V/R.
What is the difference between a series and parallel circuit?
In a series circuit, the components are connected sequentially, such that the current flows through each component in turn. In a parallel circuit, the components are connected in parallel, such that the current is split between them and flows through each component simultaneously.
