derive the formula of amp hours is calculated for 12v
battery.where no. of plates is given
how to calculate efficiency of voltage and current controlled welding transformer?
Mention the difference between Analogue and Digital circuit?
where they are using surge arrester and lighting arrester? how they connect? what is the purpose of that?
what is the minimum (Common factor) insulatin resistance of the following a, 4mm sq wire b, cable from 50 mm sq to 800mm sq
in alternator permanent magnet generator is also connected on the alternator shaft,then y that PMG voltage is very low as compared to alternator?
hi Is there any possibilities to find out the rotation of a shaft or something else by using electromagnectic waves or by IR rays.If s then can v change the dir., of rotation of the same by remotely?& how? plz dn't any1 say "NO r CAN'T"
Dear sir, we are getting voltage fluctuations suddenly for 2 or 3 minutes again it becomes normal. we checked each and every connection some times we are getting 110 volts like that from earth to neutral again it is reducing we are getting supply from 45 kva DG set give earthing properly.
Is it possible to make 0.75KW motor earthing from MCC panel by using the 1.5 SQMM, 4 core cable, means 3 core for 3 Phases & 1 core for Earth terminal?
low voltage distribution is done by a)3 phase 3 wire b)3 phase 4 wire c)single phase
What is 2P*0.5 sqmm screened copper cable and what is the use of it..?
hi frnds.....anyone get any reply from HPCL. I HAVN'T.....B,COS written will b on FEB 17 th.
What are motor generator sets and explain the different ways the motor generator set can be used ?
