I'm doing physics right now (in grade 9) and I was INSANELY confused on this topic, but you literally just taught me calculating energy in 4 minutes and my teacher couldn't do it in 2 hours....
Excellent video content! Apologies for chiming in, I would appreciate your opinion. Have you tried - Proutklarton Vanish Electricbills Plan (google it)? It is a great exclusive product for cutting your electric bill substantially without the normal expense. Ive heard some amazing things about it and my old buddy Taylor after many years got great success with it.
Hey, I am Maria from Uganda. I really liked your video for calculating the cost of electricity. I am kindly requesting you to make a video for calculating unit cost of electricity especially when time, emf, resistance and total cost of electricity are given thankyou
Thank you, this comes in very handing especially for those moving out on their own and needing to calculate expenses, however I will partially disagree with his statement at 3:59, its about the environment and the money
pls help, A TELEVISION SET IS 65W AND A REFRIGERATOR IS 1.2KW EACH ARE CONNECTED IN A HOUSE AND SWITCH ON FOR 24 HOURS IF THE COST OF ELECTRICITY IS 15 KOBO PER KWH HOW MUCH WILL IT COST?? HELP PLS ITS URGENT
*Hi, If you still need the answer to your question. You add the power of the two appliances, that's (1.2 + 0.065) KW =1.265 KW in an hour (not per hour), and you will be using them for 24 hours, that's (1.265 * 24) KWH = 30.36 KWH. Then, knowing the cost is 15 KOBO/KWH. So, the total cost is (30.36 * 15) KOBO = 455.4 KOBO.*
if an electric company charges electricity for 10 rupees per kwh how much would that be for a ,normal bulb, LED and CFL ? for each month per year pls help
I'm so sorry but can anybody explain why if the rate is 6 cent, why he multiplied the energy by 6. Instead of .06. If .10 is ten cents then I thought he would multiply the energy x .06 or does it matter?
I thought it should have been. 06 too. He should have multiplied. 45 x 100 to convert it to dollars. That would have turned .45 into 45. Divide 45 by .06 and you get 2.7 cent.
hmm... In fact you done a bug, since you modified 150W into 150W:1000. As a math teacher I must sadly tell you that that is wrong. Since now guys can read 150W:1000=0.15kW. That is wrong. Correct is (the long way) 150W = 150W * 1 = 150W * 1 : 1 = 150W * 1000 : 1000 = 150W * k : 1000 = 150kW : 1000 = 0.15kW
