04 - How to find the Equivalent Resistance of a Short Circuit

[@gautamkumarkumar1482]

very nicely explained , even better than university professors ,my all doubts were cleared keep it up bro!!

[@SkanCityAcademy_SirJohn]

Thank you very much

[@SkanCityAcademy_SirJohn]

Will you like to have series of lessons on something like these??

[@kobbiesjunior8755]

God richly bless you, please I want to ask, is it always that when 2 nodes are connected without any circuit element between them becomes a short circuit?

[@SkanCityAcademy_SirJohn]

Well, I don't get your questions, but I believe you want to know how to determine when a resistor is short in a circuit. So when you take a loop, going around the loop if you don't pass through any other circuit element except one resistor then the resistor has been short and you have a short circuit. I hope this is clear.

[@kobbiesjunior8755]

@@SkanCityAcademy_SirJohn Thank you very much, what I wanted to ask was that is a short circuit always 2 nodes that have been connected together without any circuit element between the 2 nodes

[@SkanCityAcademy_SirJohn]

Yes

Thank you so much sir for this explanation... Well Explained.. Bravo 🙏

You're welcome. Thank you for watching

[@farahkhan1128]

if there is a short circuit between two parallel resistors A and B and we connect head of resistor A with one end of short circuit and other end of short circuit with foot of other resistor B . would there be parallel or series combination between A & B?

[@SkanCityAcademy_SirJohn]

If current will pass through A and the short circuit to B then they are in series

Meanwhile, you can join my telegram tertiary group and drop the picture of the question there, so I check for you

[@danielkarikari2207]

Please the second example I don’t understand why the 2ohm is short circuited ??

[@danielkarikari2207]

I can see 3ohm beside the 2ohm and when you use the loop method current will flow through the 3ohm so please why is it that the 2ohm is short circuited

[@SkanCityAcademy_SirJohn]

there is a thin wire connected between the 4ohm and (7v + 3ohm resistor), that thin wire is a shortcircuit. The moment you can go through a loop without passing through any other circuit element except one resistor, it means the resistor has been short-circuited, regardless of the position of the resistor. so dont be confused about the position of the 2ohms resistor. just use the loop to determine it and you'll be good to go. for more explanation watch this video - kzbin.info/www/bejne/gIKpgIacipKtnqM

[@SkanCityAcademy_SirJohn]

Okay, so the 7v will drive current through the 1ohm, now at the junction, the current sees that there is a least resistant path, that is the short circuit, the all the current that flows through the 1ohm will ignore both the 2ohm and 4ohm and flow through the short circuit and return to the negative terminal of the voltage source. In that case, the 4 and 2 ohms are both short circuited

[@SkanCityAcademy_SirJohn]

Do you get it now?

[@danielkarikari2207]

Thank you boss..God bless you 🙏

[@gabbyinza3006]

good job man, thank you

[@michaelappiah-kubi684]

If you move through a loop containing one resistor and find an element which doesn't necessarily impede the current like maybe an ammeter or galvanometer...Could you still consider it to be short circuited?

[@SkanCityAcademy_SirJohn]

Yes, because an ammeter has very low resistance. In that case if it's connected in parallel with a resistor, very high current will flow in the ammeter causing damage to the device (short circuit). Hence it will still be a short circuit.

[@michaelappiah-kubi684]

Oh okay. That was very helpful. Thanks!

[@SkanCityAcademy_SirJohn]

You're welcome

[@weidong12369]

Omg thank you sir! Good explanation! But I still don’t get it why is the 2ohms resistor short circuit in the 2nd last example

[@SkanCityAcademy_SirJohn]

You're welcome. The basic idea is that when you go round a lop without passing through any circuit element except one resistor, It means that...that resistor has been short circuited... Thank you for watching... If you still don't get it, kindly let me know
