**Voltage divider circuit**is also known as potential divider circuit. Input to a voltage divider circuit is V

_{in}.

V

_{in}voltage will drive current (I) through both resistors. Because of both resistors connected in series, then the same current will flows pass through each resistor.

Effective resistance of two series resistors are R

_{1}+ R

_{2}. Drop voltage across this combination of both resistor is a V

_{in}, according to Ohm's Law, the current flowing is

I = V

_{in}/ (R

_{1}+ R

_{2})

Voltage at R

_{2}becomes

V

_{out}= I x R

_{2}

Substituting the current (I) with the first equation

V

_{out}= V

_{in}x R

_{2}/ (R

_{1}+ R

_{2})

This equation is an equation to calculate the output voltage generated by a voltage divider circuit. By selecting two resistor with resistance values suitable, we can get the value of any output voltage within the range 0 to V

_{in}(Volt).

its simple, just only seri and paraller ..

ReplyDeletein my campus i've studying ... but so hard when my teaher give me complex circuit like delta circuit. You can explaind to me about delta circuit ? Concept, formula and etc?

I am waiting you , ..
