when we short +,- terminals of battery phone get full short on power supply
but we short the (+ line and the -) line of the on off switch phone is working
how this can happen?

if we short a vbat capacitor also phone is full short.
but short a normal cap phone did not get full short?

what is the different between negative,ground,earth?

i am confusing .

help me experts

ON/OFF switch is in series & when we short its ends then its goes to in ON state (switch purpose is to short the two ends)

capacitor connected in parallel so if we short the ends it will short the two drains thats why set shows shortage

negative / erth / ground are same thing

actually negative is return patch of the current
