1
Q
what is power?
A
rate at which energy is transferred or the rate at which work is done
2
Q
what is the formula of power that includes energy transferred?
A
power (W) = energy transferred (J) / time (S)
3
Q
what is the formula of power that includes work done?
A
power (W) = work done (J) / time (S)
4
Q
what is the formula that links power, current and resistance?
A
power = current^2 (a) x resistance (ohms)
