1. ### toaster used 5h per month. it draws 8.0A pf current from a 110v outlet, electricity coasts 8c per kw*h?

a) P=V*I=110V * 8A = 880W b, c) if the toaster was running continuously (?) then it would consume E=P*t= 880W * 30 day * (24h/day) = 633600 Wh = 633.6 kWh note, 1h=3600seconds E=P*t = 633600Wh * 3600...

3. ### how to make OVER TIME go back to wages http://consumermath.org/wp-content/uploads/ PF -Practice-4.2-Calculate-Wage-Rate-Sheet-A.pdf?

I don't know where you live, but generally "overtime" is 1.5 x ordinary time and "double time" is 2 x ordinary time, as it suggests. So to convert either back into ordinary rates, you divide by 1.5 or by 2. e.g. Number 7, overtime is \$16.05, so ordinary time...

4. ### when calculating apparent power, how do you know if its leading or lagging?

Well, if the pf is given and you know nothing else, then you cannot know. ... cos (θ) The Power Factor is simply cos(θ): pf = cos (θ) Therefore we can rewrite average power as: ½...
