Webb9 apr. 2024 · That means the potential difference across R1, R2 and V1 in case of clockwise current flow is equal to zero. VR1 + VR2 + (-V1) = 0. Let’s find out the potential difference across the resistors. In case of VR1. As per the ohms law V = IR (I = current and R = Resistance in ohms) VR1 = (i1) x 4 VR1 = 4 (i1) In case of VR2. R2 is common for … WebbQuestion A 9.0 V battery has an internal resistance of 12.0 ohms . (a) What is the potential difference across its terminals when it is supplying a current of 50.0 mA?

WebbDefinition. One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. Equivalently, it is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. It can be expressed in … WebbThe electric potential difference between points A and B, V B − V A, V B − V A, is defined to be the change in potential energy of a charge q moved from A to B, divided by the … Webb12 sep. 2024 · The resistivity of a material is a measure of how strongly a material opposes the flow of electrical current.
