What is internal voltage drop and terminal voltage?
What is internal voltage drop and terminal voltage?
Last answer:
It is not permissible to just connect the positive terminal to the negative terminal of a cell with a copper wire. It will overheat and get damaged. This happens because the electromotive force (emf) ... than the nominal voltage (emf) of the cell and this lower voltage is called terminal voltage.

What kills, current or voltage?
What kills, current or voltage?
Last answer:
Current would kill. You can actually have thousands of bolts going through you and not even know it. Yes you probably know already voltage is current times resistance. Since your body is a resistor it would take just a small amount of current to create a very high voltage

If 1-phase voltage is 220V, why is 3-phase 440V and not 660V ?
Last answer:
Phase voltage =220v /( phase to neutral) Line voltage = 380 v ( phase to phase) Phase angle difference 120° So when two phases reach vmax +ve I.e. (+220v) + (+220v) = 440v that time due ... these event happen very fast. Hence we have 440 v only in three phase motor. √3.phase voltage= 380 v.
