The circuit has four identical batteries and four identical light bulbs. The current in each bulb is IL and the current provided by each battery is IB.

What is the relation between IB and IL and why?

• @Passerby I am 1st class high-school student, and this question is from 2nd class. Using my knowledge i figured that there are more than four conturs and at least IL > IB. But, I don't have the certain knowledge but electronics is my hobby and I am hoping for help from a professional(or at least person with solid knowledge) Dec 4, 2016 at 21:06
• Why does IL > IB? Dec 4, 2016 at 21:16
• I think that one light bulb gets current from more than 1 battery, so IL>IB Dec 4, 2016 at 21:19
• Imagine that you have a voltmeter, and you clipped one of the voltmeter wires somewhere in the circuit. Can you predict any of the voltages that you could measure by attaching the other voltmeter wire? Dec 4, 2016 at 21:20
