When car is started it
requires high starting
torque. This
requirement can be
fulfilled by series motor
that is why we use
series motor

Answer / apoorv

series motor has high starting torque and as its terminal voltage increases , current also increases, so it is used.

electricity requires a medium to flow and it cannot flow through air. so how does lightning come to earth through air without any medium?

I do wonder why current is present in neutral wire?i check single phase lead current feeding air conditioner...on its phase its current was 10A while same was 10A in neutral...as we know in neutral voltage is zero so if voltage is zero then how current appears on amp meter? my second observation is (just imagination)when I touch phase wire it give me shock but when i touch neutral nothing happens although as above its carrying current(amps) third but with same logic...as in simple Alternate current sine curve there is + and there is negative peak.means every time phase changing so how come every time same phase and same neutral stand (pardon for english mistakes)
