Question

What is Resistance? Can we calculate the current in a circuit with no resistors?

Answer 1

a million) Resistance is the possibility of a few supplies to stand as much as the pass of electrons throughout the time of the textile. Ohms regulation exhibits the courting between voltage, present day and resistance in a circuit, V=IR. in case you comprehend any 2 of the values you may calculate the third. case in point in case you comprehend which you have a million V and that is linked to a load that pulls a million Amp then you definately comprehend this load is a million Ohm. 2) The link exhibits a cord and a cellular. whilst the cellular is shorted out with the cellular then a huge volume of present day will pass because of the fact the resistance of the cord is extremely low and can be considered 0 for our calculations. the quantity of present day is in many cases based on the features of the cellular. the two the voltage and the resistance of the cellular influence the present in accordance to Ohm's regulation. The battery gets heat and quickly discharged.

Answer 2

Not an electrical expert.



It doesn't sound impossible to measure (calculate) electric current using other methods. A standard unit of measurement should thus then be established.

Answer 3

In a circuit like the flickr picture, the current will be undefined.



Current = volts/resistance.



Think of the battery as a perfect voltage source, in series with a resistor. The bigger the battery, the lower the resistor- and the higher the current when the battery is short circuited. (Have you heard that you must *not* short a car battery?)
