Electricity And Why It Moves Answer Key
Electrons can move but protons are held together in the nucleus by the strong nuclear force the strongest force in nature.
Electricity and why it moves answer key. Class 10 science mcqs chapter 12 electricity. Unit 9 1 electricity and why it moves period. Objects can be positive negative or neutral. Refer to the table at the bottom of the previous question for reason s.

Electricity and why it moves charge protons are held together in the nucleus by the strong nuclear force the strongest force in nature but electrons can move. Students can solve ncert class 10 science electricity multiple choice questions with answers to know their preparation level. The flow of electricity is an electric current.
If you were to take the electrons out of the wire and make them flow through space which is essentially what you do when you make a spark they can move faster but no matter what they cannot move as fast light. Electricity and why it moves charge protons are held together in the nucleus by the strong nuclear force the strongest force in nature but electrons can move. Sources and challenges answer key continued 9. Motors use electricity to produce motion.

Student answers will vary. Answer key electricity circuit glass insulators conductors electric current rubber series parallel resistor copper battery silver chose the best word s from the word box to complete each sentence. A positive object has lost electrons so it has more protons than electrons. A high potential to low potential.
A neutral object has an equal amount of protons and electrons. C in the direction of the current. Consider the particle that moves most of the time and is of the greatest interest in studying electricity. A neutral object has an equal amount of protons and electrons.
A positive object has lost electrons so it has more protons than electrons.
