A mass of 1200g is accelerated at 200 cm/s2by a force. The value of the force required is:(a) 2.4N(b) 2400N(c) 240 kN(d) 0.24N
if we look on phasor of the transformer vaoltage is 180 oppsite at primary and the secondary so to improve a power factor is secondary should kept negative to improve it primary side means is -.90 became +.90 at other side
we have 15 ampere variyac but we want 30 ampere variyac what we do
sir, Is their any measuring unit of knoking? please explian?
I just purchased a 4 position cam switch to be used to operate a 3-speed blower motor. The motor is a 10 amp motor and has 3 wires that are used to control speed. The cam switch was rated at 660V 20 amps but when I received it, I noticed that it has AC-15 operational current rating (Ie) of 4/5 amps. If I am reading the label correctly. the 4/5 amps is related to 440v/220V (Ue). Other ratings are AC-3: 5.5A, AC2: 7.5A and AC-4: 1.5A. My questions are 1) Is it safe to use this switch with the motor I have 2) what is the difference between the 20 amp Ith ratting and the Ie operational ratings?
