What is repel?
300
Given a series circuit that a voltage of 10 volts and a current of 0.1 amps, this is the value of the circuit's total resistance.
What is 100 Ohms?
300

Circuit type or arrangement using only one pathway for current to flow.

What is a series or combination circuit?

300

Electricity that forms from an uneven balance of electrons on an insulated material.

What is static electricity?

400
This electrical term describes the rate of flow of electrons in a circuit.
What is current?
400
A magnet that is created by current moving through a coil wrapped around an iron core.
What is an electromagnet?
400
A series circuit has a light bulb with 10 ohms of resistance, a led with 15 ohms of resistance and a resistor with 200 ohms of resistance. This is the total resistance of the circuit.
