Do alkynes have cis trans isomers?

In organic chemistry, an alkyne is an unsaturated hydrocarbon containing at least one carbon-carbon double bond. Alchemy and olefin are often used interchangeably (see the nomenclature section below). The acyclic…

What is the effect of a field?

Field Effect (Chemistry):¬†an effect that a pole (unipolar or dipole) has on a remote reaction center (reaction rates, equilibrium). This effect works through space not through ties that distinguish it…

Can current be negative?

Can current be negative? As from question you thought that its wrong, but no friend question is right but current is never negative but its calculation at end its as…

Can there be a potential difference without current?

The electric potential is the potential electric power per unit charge, measured in joules per coulomb (volts). The “electric potential” must be distinguished from the “electric potential” by noting that…

What is a pure inductor?

Inductors do not behave just like resistances. While the resistors simply oppose the flow of electrons through them (by lowering a voltage directly proportional to the current), the inductors resist…

What does KA mean on a circuit breaker?

A circuit breaker is an automatically actuated electrical switch designed to protect an electrical circuit from damage caused by excessive current, usually resulting from an overload or a short circuit….

What is inverse time overcurrent relay?

At this type of relay, operating time depends on the amount of drive. If the amount of drive is very high, the relay operation is very fast. In other words,…

What is the current relay?

The current start relays are used for motors with fractional power, which require a low starting torque. Its main function is to help start the engine. The start and run…
