action of voltage drop..

[Bhuvanesh Nick]

in the above circuit.what are all the voltage drop that i getting is given to led..am i right or wrong.if wrong is there any action realted to voltage drop of resistor to led clarify me plzz

 

[Pradeepbp]

Voltage drop across R1 and LED1 are same as V1 since they are connected in parallel. V(R1) = V(LED1) = V1 .

Depends from power source and from R1 value.

If you use small battery and R1 have low value this can cause voltage drop.

For example full car battery have voltage 12,72V-12,73V when cranking (apply load) voltage fall down to around 10-10,5V.

Sir if i have 1.5v supply one variable resistor and led..can i make it to glow even the requirement of led id 3v

Yes, that is possible but we must do some tricks. I use small 1,5V battery to power red LEDs in my fishing lures.
