5F Electrical Energy Transfer

Front

What is electrical energy transfer?

Back

The process of moving electrical energy from one point to another, often through conductors in a circuit.

Front

What is the unit of measurement for force?

Back

Newtons (N) are used to measure force.

Front

What is the net force?

Back

The overall force acting on an object after all the individual forces are combined.

Front

What is voltage?

Back

Voltage is the electrical potential difference between two points in a circuit, measured in volts.

Front

What is a battery?

Back

A device that stores chemical energy and converts it to electrical energy, providing a voltage difference.

Front

What is the symbol for a battery in a circuit diagram?

Back

A long line (positive terminal) and a short line (negative terminal) representing the two terminals of the battery.

Front

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

Back

Ohm's Law states that Voltage (V) = Current (I) x Resistance (R).

Front

What is the unit of measurement for voltage?

Back

Volts (V) are used to measure voltage.

Front

What is the role of a circuit in electrical energy transfer?

Back

A circuit provides a closed loop for electrical current to flow, allowing energy transfer.

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.
