Because in voltmeter resistance is high and ammeter shows negligible resistance therefore applying voltmeter in series would affect the circuit and thus voltmeter is connected in parallel

Question pad ....is it possible that magnetic field is zero.........koi jaruri thodi na hai ki hamesha koi field ho.....0 bhi ho sakta hai

1Thank You

Hitesh Kumar 7 years, 10 months ago

Not quite. If a particle moves in a straight line through a region of space, that means the net force on it is zero. If we assume that all nonmagnetic forces on the particle are already known to be zero, that means that the magnetic force is also zero: [math]f_B = q \vec{v} \times \vec{B} = 0.[/math] This does not imply that the magnetic field is zero, but rather only that the component of the magnetic field perpendicular to the charged particle's velocity is zero. In other words, the magnetic field, if it exists, is parallel to the particle velocity.
