Question

9b 1. Recall circuit IX from the tutorial, which is reproduced at right. In the tutorial, batteries A and B were identical. In this problem, you will consider two cases in which they are not. a. Suppose that the absolute value of the potential difference across battery A were reduced, but battery B is unchanged. When the switch is closed, would bulb 9b light? Explain your reasoning. A 9a B Circuit IX If you believe that bulb 9b would light when the switch is closed, draw an arrow on the diagram at right to indicate the direction of the current through it. Explain your reasoning. When the switch is closed, would bulb 9a be brighter than, dimmer than, or as bright as it was in the tutorial? Explain your reasoning. 9b b. Suppose instead that the absolute value of the potential difference across battery B were reduced, but battery A was the same as it was in the tutorial. When the switch is closed, would bulb 9b light? Explain your reasoning. A 9а Circuit IX If you believe that bulb 9b would light when the switch is closed, draw an arrow on the diagram at right to indicate the direction of the current through it. Explain your reasoning. When the switch is closed, would bulb 9a be brighter than, dimmer than, or as bright as it was in the tutorial? Explain your reasoning.

please keep the answer simple and clear

Answer 1

Soin. 4.971 191 B (a) VA'<NA Cold vooldage) NA UB i) Yes Ib bulb would ligne, because here Still there is potential difference presine in the cioucit accooss bulb Ib which causes to usant How through it. ii) using kun in Outer loop here in Using KNL hare we necie gel, In outer loop again Ni - vg's ET Since VAT V so I is disceted to the Right a Rab 1 I Ti in) as helic VA'=VA ga Mo-IRA - NO=0 Val-ro= I Rob AS WAT NG B. I Now but due to reduction in Vo here total current in the cireuil Inercar circuil Inercar which when increase 외 3. Pa' = L 'xva, P's p flere Bulb la heil brighten than as it was in the tutorial. glow i. Iz is to the right in) as here MA > vb. so that in parallel connection power will be grew as, P = uxa ul> vo 81 h PAP bell (WA) < Vans New Here ga bulb were be brighten them. In bul be dimmer than as it it nelie was in the tutorial. b) is No' < Na (old voltage) , VANA Yes ib bulb well ligne well light here also because still here there will be some potential difference in the circuit which Causes corend to flowa
