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.
