Hi guys, now in this film, this is circuit that we are given to us. And in this circuit, if I dr

Here we will solve this problem by using nodal analysis method. In the circuit, after interchang

Here we will solve this problem by using nodal analysis. Let's say that this is the node number

So here this is current i1 and this is i so we can write e1 minus e2 equal i 1 r1 so 1 .5 minus

In this question given that E1 is equal to 12 volt and E2 is equal to 31 volt. R1 is equal to 1

Question

Consider the following figure. (Assume R1 = 7.60 Ω, R2 = 5.90 Ω, and e m f = 16.0 V.) An open circuit begins at point a with a wire extending horizontally leftwards until it reaches a 4.00 V battery with the positive terminal on the left. After the battery, the wire splits into two branches. One branch continues left to a resistor R1, turns downwards and continues to a battery with emf ℰ with the positive terminal on top, and then turns rightwards. The other branch goes downwards and contains a resistor R2. The two branches recombine and the wire extends rightwards until it reaches a 10.0 Ω resistor before ending at point b. (a) Calculate the magnitude of the potential difference between points a and b in the figure above. (b) Identify which point is at the higher potential.
