Web2 days ago · If the resistance of an electric circuit is 12 ohms and the voltage in the circuit is 60 V, the current flowing through the circuit is A. 60 A. B. 0.2 A. C. 720 A. D. 5 A.
Current when resistance is zero
Did you know?
WebWhen the resistance in any circuit is equal to zero then the current passing through that circuit will be infinite. We know from Ohm’s law that V=IR. Here, if you consider … WebMar 17, 2024 · The relationship between current and voltage depicts what kind of resistance your circuits are working with. The Purely Resistive AC Circuit. A circuit that contains only a pure resistance (ohms) in an AC circuit is called a Purely Resistive AC Circuit. From a technical standpoint, this circuit does not contain capacitance or inductance.
WebDetermining resistance ##### Assume V 0 between terminals ⇒ Find E ⇒ Find J=σE ⇒ ... A boundary between two lossless dielectrics has zero surface charge and surface current Boundary Conditions A perfect conductor has zero … WebTheoretically, if resistance R = 0 , according to Ohm’s law current (i = V/R) is infinite. Infinite or very high current may burn the circuit. Practically, even if there is no resistor in a circuit, the wires used to construct the circuit have at least a little amount of resistance. Cells also offer internal resistance.
WebSince lines on a schematic represent perfect zero-resistance conductors, there is no rule that says lines from multiple elements are required to meet in a single point junction. ... That lower resistance raises the current (ohm's law) because the voltage is the same, which damages what the current was originally going through (in your example ... WebSep 12, 2024 · The amount of resistance to the flow of current within the voltage source is called the internal resistance. ... If a wire is connected across the terminals, the load resistance is close to zero, or at least considerably less than the internal resistance of the battery. Since the internal resistance is small, the current through the circuit ...
WebCurrent tends to move through the conductors with some degree of friction, or opposition to motion. This opposition to motion is more properly called resistance. The amount of current in a circuit depends on the amount of …
WebApr 20, 2024 · 0 As electric current will flow in path with zero resistance when a zero resistance path and finite resistance path are in parallel combinations. In a Wheatstone bridge, the resistors have a finite … download snagit 13 with keyWebSep 15, 2015 · Even if you were to consider a superconductor as a wire (where resistance really is zero), it still has an inductance value. When resistance is very small (or zero), the inductance becomes significant. It will prevent the current from increasing faster than a … class to find badi in sapWebNov 25, 2013 · so when R is zero, as is the case for a short circuit, then V will be zero as well, no matter how high the current I is. I × 0 Ω = 0 V The current is caused by a potential difference in the circuit as a whole, it doesn't have to be between any two points. download snagit 2019 full crackWebMay 28, 2024 · Because the resistance is non-zero, some power will be dissipated.
