pimpchi:We are to answer only the calculation right ? |

Loris576: If you can answer all the way cool, if not you win 500 naira airtime |

pimpchi: Here it is For 1. Kirchoff voltage law was used 2. Step up 3. No .. step up is designed to increase the supply voltage while step down is to decrease it.. so dey cannot be used interchangeably

pimpchi: pimpchi:Primary voltage (Vp) = 110 V Numbers of primary turns (Np)= 1400 turns Numbers of secondary turns (Ns) = 3610 turns Secondary voltage (Vs) = ? But Vp/Vs = Np/Ns Vs = (Vp × Ns)/Np Vs = (110 × 3610)/1400 Vs = 283.6 V We can use the Vs gotten above to calculate Secondary Current (Iload) using the resistance (load) given.. Load = 3.9 × 10³ ohms That is; Vs = Iload × load Iload = Vs/load Iload = 283.6 ÷ 3.9 × 10³ Iload = 0.073 A To calculate primary current (Isource); we use the expression below Vp/Vs = Iload/Isource Isource = (Iload × Vs)/Vp Isource = (0.073A × 283.6V)/110V Isource = 0.188 A Isource = 0.188 Amperes and Iload = 0.073 Amperes |
