Capacitor and Direct Current (DC) - Dielectric

Capacitor and Direct Current (DC) – Dielectric

Capacitor and Direct Current

If a battery is connected to a capacitor, it will allows no direct current (DC) to flow through. If a not charged capacitor is connected across the terminals of a battery, a transient current flows as the capacitor plates charge up.

Capacitor and Direct Current. Current starts from its maximum value and decreases to 0 amps. This current is called “transient current”.

What is Electrical Resistance? Obtaining a material’s resistance

What is Electrical Resistance? Obtaining a material’s resistance

The electrical resistance is a measurement of the opposition that offers a material to the passage of electrons (the electric current). When a material, such as metals has many free electrons, it allows the easy flow of electrons and it is called conductor.

Resistors in series and parallel (Equivalent resistor value)

Resistors in series and parallel (Equivalent resistor value)

Resistors in series and parallel How to obtain the equivalent resistor value of resistors in series and parallel. Resistors in series To implement a circuit with resistors in series you have to connect one resistor after the other one. (see the image). The equivalent resistor value of the resistors connected in series is equal to the […]
