Ohm's Law and Electric Circuits (Physics)

Front

What is Ohm's Law?

Back

Front

Define voltage.

Back

Voltage, also known as electric potential difference, is the measure of the energy per unit charge available to drive the flow of electrons in a circuit. It is measured in volts (V).

What is current in an electric circuit?

Back

Current is the flow of electric charge in a circuit, measured in amperes (A). It represents the rate at which charge is flowing.

Front

What is resistance?

Back

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

Front

What is the unit of electric current?

Back

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

Front

What is the relationship between voltage, current, and resistance?

Back

Front

What happens to current if resistance increases while voltage remains constant?

Back

If resistance increases while voltage remains constant, the current will decrease according to Ohm's Law.

Front

What is a short circuit?

Back

A short circuit occurs when there is a low-resistance connection between two points in a circuit, allowing current to flow along an unintended path, which can cause overheating and damage.
