Chapter, Special Trackwork, Track Design Handbook, Light - Question 10 to calculate capacitance, which of the subsequent formulation is proper v = q/c v = c/q q = v/c q = c/v question eleven if a modern of 12.5a flows for a time of two mins calculate the quantity of rate transferred one hundred fifty volts 1500 farads 1500 coulombs 9.6 coulombs query 12 if a price of 500 micro coulombs is saved in a 25 micro farad capacitor, what is going to the p.D. Throughout the plates be? Zero.2 volts 20 volts 12500 milli volts 1250 milli volts question thirteen calculate the fee if a two hundred micro farad capacitor is conected to a 200 volts supply 0.04 coulombs zero.4 coulombs 0.04 joules 0.Four joules query 14 calculate the equal capacitance of three capacitors when related in series. There values are : 5 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 electrical subject strength of a capacitor is decided through the voltage among the plates divided by the thickness of the dialectric. However what devices are electric powered field energy measured in ? Coulombs consistent with rectangular metre amps in line with 2nd volts according to metre watts in step with 2d question 16 which is correct formula for calculating the energy saved in a capacitor e = 0.5cu2 e = 0.5li2 c = w/zero.5u u = w/0.5c .
Query five calculate the power saved in a 200 micro farad capacitor connected to a 200 volt deliver correct answer: four joules bear in mind e = zero.5cu2 question 6 if 3 10 micro farad capacitors are related in series, the charge on each capacitor can be correct answer: the equal question 7 why are discharge resistors regularly connected to big capacitors accurate answer: to safely dissipate the charge held for that reason lowering shock hazard question eight what's the method had to calculate the electricity stored in an inductor? Accurate solution: e = zero.5li2 question 9 on an ac mains supply of 230volts, what is the minimal voltage price which capacitors have to be rated at? Accurate answer: four hundred volts .
Query 10 to calculate capacitance, which of the subsequent formulation is true correct solution: v = q/c query eleven if a contemporary of 12.5a flows for a time of two mins calculate the quantity of price transferred correct solution: 1500 coulombs recall the fee is q and q=ixt query 12 if a price of 500 micro coulombs is saved in a 25 micro farad capacitor, what's going to the p.D. Throughout the plates be? Accurate answer: 20 volts query thirteen calculate the fee if a 2 hundred micro farad capacitor is conected to a two hundred volts supply correct solution: 0.04 coulombs question 14 calculate the equivalent capacitance of 3 capacitors while related in series. There values are : five micro farad, 10 micro farad and 30 micro farad correct solution: 3 micro farad query 15 the electrical subject power of a capacitor is decided by way of the voltage between the plates divided via the thickness of the dialectric. But what devices are electric discipline energy measured in ? Correct answer: volts according to metre bear in mind e = u/d query sixteen that is correct components for calculating the power stored in a capacitor accurate answer: e = 0.5cu2 query 17 as a widespread rule, whilst a capacitor is fully charged what's going to it block? Correct solution: a d.C. Modern query 18 the capacitor outfitted within the starter transfer of a fluorescent light fitting is for what purpose ? Correct solution: to suppress radio frequency interference .
