When a 1.50v battery is shorted by a copper wire whose resistance can be ignored, the current through the copper wire is 2.75 a. what is the internal resistance of the battery?

Internal resistance = 0.545 ohm

Explanation:

As per ohm's law we know that

here we know that

i = electric current = 2.75 A

V = potential difference = 1.50 Volts

now from above equation we have

now we have

overcharge is the right answer system

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
