can it be converted ? (like 15w = 6v ) like tht... ?
actually what tht means ?

Answer / kumaran
Amps = Watts / Volts
How ?
1 Watt = 1 Joule/Second
1 Volt = 1 Joule/Coulomb
(a Coulomb is a unit of electrical charge).
Ampere = 1 Coulomb/Second
So that,
Amps = Watts / Volts
(OR)
W=A*V
15W=2.5A*6v is your answer

Answer / tapendra
wattage= unit of power
voltage= presure of charge
w=v*i (v=voltege & i=current)
so 15w=6v*i
i=2.5
15w = 6v*2.5 amp

Answer / mahantesh
I=W/V;
I=V/R;
Therefore V/R=W/V;
V^2=W/R;
36=15/R;
R=2.4 ohms.
