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 4002What 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 thanks
2 7492How 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 ? thanks
2 6617how 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 3606can 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 thanks
