Front

What happens to positive electric charges when they interact with other positive charges?

Back

They repel positive charges and attract negative charges.

Front

What is attracted to the south pole of a magnet?

Back

The north pole of a magnet.

Front

How can you increase the strength of an electromagnet?

Back

By increasing the current, adding iron to the core, and increasing the number of coils on the magnet.

Front

What is voltage?

Back

The potential electrical energy or push that makes electrons flow.

Front

What is the relationship between electric charge and electric force?

Back

Like charges repel each other, while opposite charges attract.

Front

What is the unit of electric current?

Back

Ampere (A).

Front

What is the principle of electromagnetic induction?

Back

A changing magnetic field can induce an electric current in a conductor.

Front

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

Back

A capacitor stores electrical energy temporarily.

Front

What is Ohm's Law?

Back

The relationship between voltage (V), current (I), and resistance (R) is given by V = I × R.
