NGSS.HS-PS2-4

The place from which electrical current is produced such as a battery, a wall outlet, a generator, or a solar panel.

• Current transformer

• Voltage Source

• Power regulator

• Electrical device

A device that opposes the flow of electricity such as a lamp or a motor.

• Resistor

• Transistor

The main difference between a resistor and a transistor is that a resistor limits the flow of electrical current, while a transistor amplifies and switches electrical signals
