For the following, put T in the box if the statement is true, Fif it is false. Try to provide a very brief explanation of each answer.
a) Like chargs attract; unlike charges repel.
b) When polythene is rubbed with wool, positive charges move from the polythene to the wool.
c) Metal water pipes in the home can be used as an electrical earth.
d) The tip of a lightning conductor should have a sharp point.
e) It could be dangerous to fly a kite during thundery weather.
f) Blobs of solder on electrical equipment should be rounded rather than pointed.
g) A conductor allows protons to move through it easily.
thank you for your time!
a) T (True) - Like charges repel each other because they have the same electrical charge, whereas unlike charges attract each other because they have opposite electrical charges.
b) F (False) - When polythene is rubbed with wool, negative charges actually move from the wool to the polythene. This is known as the triboelectric effect.
c) T (True) - Metal water pipes in the home can act as a pathway for electrical current to flow into the ground, providing a safe path for electrical charges and serving as an electrical earth.
d) T (True) - The tip of a lightning conductor should have a sharp point to facilitate the discharge of lightning safely into the ground.
e) T (True) - It could be dangerous to fly a kite during thundery weather because kites can act as conductors of electricity and increase the risk of being struck by lightning.
f) T (True) - Blobs of solder on electrical equipment should be rounded rather than pointed. This helps to distribute the heat evenly and minimize the risk of damage or short circuits.
g) F (False) - A conductor allows electrons, not protons, to move through it easily. Electrons are negatively charged particles, whereas protons are positively charged particles.
