Front

What is the role of a capacitor in an electrical circuit?

Back

A capacitor stores electrical energy temporarily and releases it when needed.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R). It is expressed as V = I * R.

Front

What is the difference between AC and DC current?

Back

AC (Alternating Current) changes direction periodically, while DC (Direct Current) flows in one direction only.

Front

What is resistance in an electrical circuit?

Back

Resistance is the opposition to the flow of electric current, measured in Ohms (Ω).
