Why are some relay circuts designed to have the ct current flow through the neutral instead of the phase wire, such as in some diff relays?1 2384
What are the difference between these terms ? e.m.f, voltage, potential, potential difference, current etc? what are the difference between these terms ? (electromotive force) e.m.f, voltage, potential, potential difference, reference potential, reference potential difference, current. How can i explain and describe these all terms in single line each and little more explaination too thanks2 5163
How to check the specific gravity of the two 12 V batteries connected in series to a 24 V UPS and inverter ? will we have to disconnect all the connections and turn off the UPS and inverter or not ? will we have to check specific gravities in each cell of the two batteries ? what is the name of the instrument that is used to check the specific gravity and whats the procedure to check the specific gravity with it ? thanks2 4236
how one can check the Current of a DC 12 V battery ? Procedure. I told that take a thick wire (having more wires in it) and then join the + and - terminals of battery with the help of two ends of a thick wire .... is this correct or wrong .....1 1993
can you check the current and voltage of a 12 V battery by a digital multimeter in this fashion that apply the digital multimeter across the battery terminals directly ? say yes or no ... i sais yes ........... is this true or false ? plzz tell me and also explain ........ plzz thanks4 2900
