Electrical Wiring Residential Chapter 4 Answers - Question five calculate the strength stored in a 2 hundred micro farad capacitor linked to a 200 volt deliver accurate answer: 4 joules recollect e = 0.5cu2 question 6 if 3 10 micro farad capacitors are linked in series, the price on every capacitor may be correct solution: the equal question 7 why are discharge resistors often related to huge capacitors correct solution: to soundly burn up the charge held for that reason lowering surprise danger query eight what's the components had to calculate the strength saved in an inductor? Accurate answer: e = zero.5li2 question nine on an ac mains deliver of 230volts, what is the minimal voltage price which capacitors have to be rated at? Accurate solution: 400 volts .

Question 10 to calculate capacitance, which of the subsequent formulas is proper v = q/c v = c/q q = v/c q = c/v query eleven if a present day of 12.5a flows for a time of 2 mins calculate the quantity of charge transferred a hundred and fifty volts 1500 farads 1500 coulombs nine.6 coulombs query 12 if a charge of 500 micro coulombs is stored in a 25 micro farad capacitor, what is going to the p.D. Across the plates be? 0.2 volts 20 volts 12500 milli volts 1250 milli volts query thirteen calculate the price if a 200 micro farad capacitor is conected to a 200 volts deliver zero.04 coulombs 0.4 coulombs 0.04 joules zero.4 joules query 14 calculate the equivalent capacitance of 3 capacitors when connected in collection. There values are : five micro farad, 10 micro farad and 30 micro farad 2 micro farad zero.02 micro farad 0.33 micro farad 3 micro farad query 15 the electric area power of a capacitor is determined by way of the voltage among the plates divided via the thickness of the dialectric. But what devices are electric powered field electricity measured in ? Coulombs per square metre amps consistent with second volts according to metre watts consistent with 2nd question sixteen which is accurate formulation for calculating the electricity saved in a capacitor e = zero.5cu2 e = 0.5li2 c = w/0.5u u = w/zero.5c .

Query 10 to calculate capacitance, which of the subsequent formulation is proper correct answer: v = q/c query 11 if a contemporary of 12.5a flows for a time of two minutes calculate the quantity of rate transferred accurate answer: 1500 coulombs do not forget the rate is q and q=ixt query 12 if a fee of 500 micro coulombs is stored in a 25 micro farad capacitor, what will the p.D. Throughout the plates be? Accurate solution: 20 volts question thirteen calculate the price if a 200 micro farad capacitor is conected to a 2 hundred volts deliver accurate solution: zero.04 coulombs question 14 calculate the equal capacitance of 3 capacitors when connected in series. There values are : 5 micro farad, 10 micro farad and 30 micro farad accurate answer: three micro farad question 15 the electric area power of a capacitor is decided with the aid of the voltage between the plates divided with the aid of the thickness of the dialectric. However what devices are electric powered area electricity measured in ? Accurate answer: volts per metre remember e = u/d query 16 that's correct formulation for calculating the energy saved in a capacitor correct answer: e = zero.5cu2 question 17 as a wellknown rule, whilst a capacitor is absolutely charged what will it block? Accurate answer: a d.C. Cutting-edge question 18 the capacitor fitted within the starter switch of a fluorescent mild fitting is for what motive ? Accurate solution: to suppress radio frequency interference .
