Voltage Divider – Voltage Division – Series Resistors

Marcel — Fri, 19 Apr 2024 18:18:19 +0000

The voltage divider is a circuit that allows us to obtain an output voltage less than the input voltage. The output voltage is normally obtained across ground and the resistor connected to it, but it could be across any of the other resistors.

Maximum Power Transfer Theorem Explanation

Marcel — Wed, 17 Apr 2024 17:50:52 +0000

What does the Maximum Power Transfer Theorem say? “The maximum power transfer to the load is obtained when the load resistance RL is equal to the internal resistance of the source Ri”. But why is that the case? Real voltage sources have the equivalent circuit shown in the figure below, where V = I x [...]

What is Direct Current? – What is DC?

Marcel — Tue, 06 Aug 2019 17:17:25 +0000

Direct Current (DC), is the result of the flow of electrons (negative charge) in a conductor (most of the time, wires of copper) that goes only in one direction.
