Five identical cells each of resistance 1 ohm
WebFeb 3, 2024 · The net internal resistance between a and b is 3 A. Explanation: Here 4 cells each having emf e = 1.5 V and internal resistance are connected in series. So total resistance of the circuit will be As one of the cell is connected in reverse direction the effective emf becomes E = 3 ⋅ e − e = 2 e = 2 x 1.5 = 3 V Web1 hour ago · To obtain a high-quality product and avoid undesirable processes, such as the dissolution of the platinum anode at a low content of Li 2 O in the melt, i.e., ~0.25–0.50 wt.%, the lack of solubility of plutonium and americium oxides at high contents of Li 2 O, at ~3.4 wt.% and ~5.1 wt.%, respectively, or the degradation of structural materials ...

WebNov 26, 2024 · We have calculated the resistance of this bulb. And once we know the resistance, we can treat this as a simple circuit problem, which we have solved before. So, let me just go ahead and redraw that. So our circuit now has a resistance of two ohms, and it is connected across a five volt, five volt battery, five volt cell. WebDec 21, 2024 · The Ohm's law formula can be used to calculate the resistance as the quotient of the voltage and current. It can be written as: R = V/I. Where: R - resistance. V - voltage. I - Current. Resistance is expressed in ohms. Both the unit and the rule are named after Georg Ohm - the physicist and inventor of Ohm's law.
WebThree identical cells each of emf 2V and internal resistance 1 Ω are connected in series to form a battery. The battery is then connected to a parallel combination of two identical resistors, each of resistance 6 Ω. Find the current delivered by the battery. Medium Solution Verified by Toppr WebFour cells, each of emf E and internal resistance r, are connected in series across an external resistance R. By mistake one of the cells is connected in reverse. Then the current in the external circuit is: Medium View solution > In the figure shown, battery 1 has emf = 6V, internal resistance =1Ω.
WebEach subpart: 1.5 Marks each The labelled circuit diagram is shown below. (a) Total resistance = 1.6 + 0.1 × 4 + R1 = 1.6 + 0.4 + R1 = 2 + R1 Total EMF = 2+2+2+2=8V We know that I = T otal EMF T otal resistance ∴ 2= 8 R1+2 or 2R1+4= 8 or 2R1 = 8−4= 4 or R1 = 2Ω ∴ Total resistance = R1+2 = 2+2= 4Ω (b) Potential difference across R1 = I R1 = …
