I'm really sorry, but I don't understand what you mean?
Why does 's/hr' then mean it converts to joules from watts?
Apologies, u have a challenge on ur hands with me.
My problem isn't physics, but maths. You're going to tell me they're the same huh?!
m really
The question:
Calculate the energy used by the lamp in 6 hours of use.
The answer:
P=V.I.t
P= 240v X 0.2A X 6hrs X 3600s
P= 1036800W!?
I thought energy was Joules? Why has the answer been given in watts? Please help!
