1.assume i am riding a motorcycle at 100km/h, but i ride the motorcycle inside a very long train which is moving at also 100km/h. What speed do i have reported to the world? 200km/h?
2.what happens at a short circuit? practically there is no resistance so the value of the current is infinity? therefore 3v battery can generate infinite curent if the wires have 0 resistance?
3.is ot possible to have such a great resistance inside a circuit in order to stop a circuit from working? same as an open circuit?
Thank you!
