[tex]P=IV[/tex] ,where P is power, I is current, and V is voltage.

Using V=IR, you can convert that to whatever you need.

"A torch bulb has 3V; 0.5A written on the packet.

Calculate the power conversion for the bulb in normal use."

So do I need to use the formula - see I'm unsure with the units. Would the answer therefore be 1.5 something?

V is measured in J/C, I in C/s, so IV in (J/C)(C/s)=J/s=W or Watts.
