Total volage drop = source voltage. |

v=i1r1+i2r2+....i5r5 Vi=IiRi(voltage drop across each resistor ) i=1,2,3,.... V=V1+V2+V3+V4+V5 V=6+6+6+6+6=30V |

@Kumar Thanks for your explanation. |

The series circuit voltage is different, current is same here each resistor has 6V hence the V=V1+V2+V3+V4+V5, {6+6+6+6+6=30V} the source voltage is 30 volts. |

5 resistor having same voltage drop 6v means they are having a same resistance. Therefor 5*6 = 30v. |

Vs=-Vd. hence Vs+Vd=0. number of resistors=5. voltage drop on one resistor=6V. Total Voltage drop(Vd)=6*5=30. Vs=-Vd. so vs should be 30 to equalize the equation vs+Vd=0. |

He is not given that they are equal voltage, then how it is 30v? It depends on R or I value. |

D.Jyothi said: (Aug 30, 2018) | |

Here, it is no equal resistance. How does it say 30v? If he gave they are equal resistance, then it becomes 30v, right? Anybody solve this. |

@D.Jyothi. Series circuit means current same and here also given voltage drop that means resistor of all branches must be equal or same. |
