NDSMELODY:Sensitivity, S = 0.1 kΩ/V Vs = {5/(25+5)} × 30 V = 5V Rs = 0.1 kΩ/V × 5V = 0.5 kΩ 1/R = 1/Rb + 1/Rm + 1/Rs 1/R = 1/5 + 1/2 + 1/0.5 1/R = 2.7 R = 1/2.7 = 0.37 kΩ Vo = {5/(25+0.37)} × 30 Vo = 5.912 V Phone no: 09062114822 - MTN |

How can I be solving someone's assignment just because of 200 naira recharge card? Tufiakwa. 1 Like |

bluefilm:i do not know how this negative thought came out from ur mind,what u dnt know is that i have the solution with me already i am only doing this from passion.do you remember that no tertiary institution is session talkless of giving out assignment to their student because the question above is not from secondary school as you think.......if u cannt solve it just view and leave, you do not need to distrupt the open minded people that will try their luck...have a good day. |

NDSMELODY: Nwoke m go and do your assignment and leave me alone. You want me to come here and be solving your EE251 assignment for you just for 200 naira airtime abi? School wan resume now naim you come remember say dem give una assignment wey you never do, so you come carry am come nairaland make boys help you solve am on the promise of 200 naira recharge card. Guy abeg no make me vex for you o. |

bluefilm:would you like me to provide solution right now?.......... |
Re: Solve This And Win A Recharge Card Part 2! by kolad59: 9:14am On Oct 12, 2020 |
NDSMELODY: Sensitivity=0.1kπ/V Internal resistance of the meter=maximum voltage range *sensitivity rm= 10*0.1=1kπ Rt= (Ra *rm)/(Ra+rm) Rt=(1*5)/(1+5)=0.83kπ USING POTENTIAL DIViDER RULE, Vm= (30 * 0.83)/(0.83+2) Vm=8.799V. Hence, the reading of the meter Is 8.799v Airtel===08122980420 |

NDSMELODY: No. Wait lemme solve it for you first |

bluefilm:if you get it right i will double the amount |
Re: Solve This And Win A Recharge Card Part 2! by bluefilm: 9:52am On Oct 12, 2020 |
NDSMELODY: Sure |

Resistance in parallel sec= ((5*10^3)*(2*10^3))/(5*10^3)+(2*10^3) =1.429kohms the voltage on the meter now is =(1.429*10^3)*30V/(25*10^3)+(1.429*10^3) = 1.62V 08132209303 MTN |

Ugobest101:where is your solution |
Re: Solve This And Win A Recharge Card Part 2! by bluefilm: 11:02am On Oct 12, 2020 |
Solving for Resistance in Parallel first gives: 1/5 + 1/2 = 7/10 Therefore, inverting the result gives Resistance in Parallel = 10/7 Kohms Total Resistance in the circuit = 25 Kohms + 10/7 Kohms = 185/7Kohms Applying ratios... Voltage across multimeter = (Resistance across multimeter/Total Resistance in the circuit) * 30V = [ (10/7) / (185/7) ] * 30 ~ 1.6216 V |

bluefilm:wrong,is this how i will score zero if it is an assignment? |
Re: Solve This And Win A Recharge Card Part 2! by NDSMELODY(m): 11:14am On Oct 12, 2020 |
Should i post my own solution? |
Re: Solve This And Win A Recharge Card Part 2! by bluefilm: 11:22am On Oct 12, 2020 |
NDSMELODY: kolad59: Sorry, I missed the sensitivity factor So, here's it again Solving for the sensitivity factor, the resistance of the voltmeter = 0.1 * 10 = 1Kohm Therefore total resistance of the Voltmeter = 2 + 1 = 3Kohms Now solving Resistance in Parallel first gives: 1/5 + 1/3 = 8/15 Therefore, inverting the result gives Resistance in Parallel = 15/8 Kohms Total Resistance in the circuit = 25 Kohms + 15/8 Kohms = 215/8Kohms Applying ratios... Voltage across multimeter = (Resistance across multimeter/Total Resistance in the circuit) * 30V = [ (15/8 ) / (215/8 ) ] * 30 ~ 2.093 V |
