Electric Current & Ohm's Law P1

Front

What are conductors?

Back

Materials that allow electric current to flow easily, such as metals like copper and aluminum.

Front

What is the unit for electrical power?

Back

Watt (W)

Front

What energy transformation occurs in a toaster?

Back

Electrical energy (e-) is transformed into heat energy (H).

Front

What is Ohm's Law?

Back

The relationship between voltage (V), current (I), and resistance (R) in a circuit, expressed as V = I × R.

Front

What is resistance in a circuit?

Back

The opposition to the flow of electric current, measured in ohms.

Front

What is the formula to calculate resistance?

Back

Resistance (R) = Voltage (V) / Current (I).

Front

What is the role of a generator?

Back

A device that converts mechanical energy into electrical energy.

Front

What type of energy transformation occurs in a generator?

Back

Electromagnetic energy (EMR) is transformed into electrical energy (e-).

Front

What is current?

Back

The flow of electric charge, measured in amperes (A).

Front

What is voltage?

Back

The electric potential difference between two points, measured in volts (V).
