A Voltage Divider Dialogue
In case you are in an introductory stage electrical engineering course you may have most likely heard of a voltage divider. Different folks which may be taken with studying about voltage dividers embody electricians, laptop engineers, communication engineers, software program engineers, and the technical crowd on the whole.
I’ll focus on this idea right here with out graphs or equations so naked with me. Take into account a field that may comprise a single supply or another mixture of circuit components. It is going to be attached to a couple resistors which can be all lined up in parallel and we have to calculate the voltage drop throughout every of the resistors. With the intention to correctly perceive voltage dividers you need to perceive the essential ideas behind Kirchoff’s Present Regulation and Kirchoff’s Voltage Regulation (KVL). Right here we will likely be making use of KVL to the resistors that I simply spoke about. The regulation says that the cumulative drop in potential (voltage) throughout all the sequence resistors will sum to the worth popping out of our supply (field). The voltage potential will begin on the worth of the supply, and drop a sure share as every of the resistors components is encountered.
These voltage drops are calculated utilizing a voltage divider. Take into account two resistors in parallel. With the intention to calculate the voltage dropped throughout the first resistor we have to multiply our voltage supply by the worth of that resistor after which divide the that worth by the whole resistance (add each resistors collectively as a result of they’re in sequence!). The ensuing worth is the voltage drop throughout that first resistor. Consequently, that leaves Vsource – Vresistor1 as the worth that’s left to drop throughout the second resistor!
Now you possibly can apply this idea to calculate the variations in voltage potentials for nearly any circuit and it’s on of a very powerful instruments you possibly can be taught.
