What is basic of electrical?
Let’s start with three very basic concepts of electricity: namely, electric charge, electric current, and electric circuit. Protons have positive charge, electrons have negative charge. Electric current refers to the flow of the electric charge carried by electrons as they jump from atom to atom.
What is current in electrical?
An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. The SI unit of electric current is the ampere, or amp, which is the flow of electric charge across a surface at the rate of one coulomb per second.
How to answer the most common electrical questions?
Below you can find calculations and answers on all above questions. You shouldn’t peek before trying to solve questions by yourself 🙂 V 2 = ? , I 2 = ? ILS = (1/√3) × (N 1 /N 2) × I LP = 12√3 × 10Amp. = 120√ 3 Amp. ILS = 12/√3 × 10 = 40√3Amp. Further: E a =V-I a (R a +R Se ) = 220 – 2I a (equation 2) Ia = 4.32 Amp.
