Electric Current

Front

What is static electricity?

Back

Static electricity is an electric charge that builds up on a material, often due to friction.

Front

What type of charge do electrons carry?

Back

Electrons carry a negative charge.

Front

Is the negative side of a battery the higher potential?

Back

False, the positive side of a battery is the higher potential.

Front

In the formula F_e = k * (q1 * q2) / r^2, what does 'q' represent?

Back

'q' represents the electric charge.

Front

What is an electric circuit?

Back

An electric circuit is the path which the electric current takes.

Front

What is electric current?

Back

Electric current is the flow of electric charge, typically carried by moving electrons.

Front

What is the unit of electric current?

Back

The unit of electric current is the Ampere (A).

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 resistance in an electrical context?

Back

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

Front

What is the difference between AC and DC current?

Back

AC (Alternating Current) is the flow of electric charge that periodically reverses direction, while DC (Direct Current) flows in one direction only.
