quick question

[NWDS]

What happens to the power output in a resistive circuit if the voltage doubles ??, would it be the same for an inductive circuit.

Thanks for looking.

Firstly the power quadruples.

Secondly, no change.

hi

if you double the voltage, you double the current so the power quadruples...

hows that for quick!

 

[the doctor]

hi

for an inductive circuit it doesnt matter if you double the voltage, the power is still nil....in theory anyways;\

 

[the doctor]

hi

nope

VxI =P

2Vx 2I= 4P....

hinope

VxI =P

2Vx 2I= 4P....

why can't we double voltage and keep current the same? (increase resistance)

 

[The Godfather]

why can't we double voltage and keep current the same? (increase resistance)

Because in this example we are increasing (doubling) the voltage, resistance is constant.

you edited your thingy!

 

[the doctor]

hi

if you have a fixed resistance and apply a voltage ,a current will flow....

if you double the pressure( voltage) then double the current must flow

because we all know V = I x R

so also I = V / R

and we know Power = I x V

swapping the 'I' in the above formula

means that power = (V/R) x V

or Power = ( VxV ) / R

e.g. Power = V

Your contribution as always (detailed) is most appreciated.

hi

the op asked about inductive circuits

if it is pure inductive,(theoretical with no resistance) then it has no power no matter what voltage is applied as the V and I are 90 degrees out of sync....

i am like edison, i hate acPray

google " battle of the currents"

!00 w lamp powered by 240v = lamp glows and lights up the room.

100w lamp powered by 415v = lamp glows very brightly and explodes.
