Anyone noticed that during lecture there were no ADS.... That's excellent sir.... for not distracting students during lecture... 😃☺☺👌👌

Amazing sir mera electricity chapter bahut weak tha lakin aab bahut strong Ho gaya Thank you sir

[shivamvats]

A circuit is composed of conductors (wire), power source, load, resistor, and switch. A circuit starts and ends at the same point. Usually, copper wire without insulation is used as a conductor. A switch is used to make or break a circuit. Resistors control the flow of the electric current in a circuit. A resistor is a passive element which means that it only consumes power but does not generate power. A load in a circuit consumes electrical energy and converts it into other forms of energy like light, heat, etc. A1/R eq =1/R 1 +1/R 2. Req< min {R 1, the R 2 }

i) 25
ii) 9 ohm = 2 in parallel with 1 in series
4 ohm = 1 in parallel with two in series

[bapugaming]

It's amazing that Sir is not disturbed by any person going and coming in the room

[theindian]

Sir aap prabu ho jinke physics teacher ache se nhi smjh pate hai school me .

🥇🥇🥇🥇

[gauravkumarsingh]

Sir the and of first question is (D) 25
And and of second question is (I)__two resistance in parallel and one resistance in series= 9 ohm
(ii)_two resistance in series and one resistance in parallel.__4ohm

[pransu]

Both the challenger problems of previous lecture also solved successfully 🤟 and also solved both the previous year numericals homework questions 🤟🤟

[nonimonitha]

He made me believe electricity is not boring moreover he reads the doubt of your mind so he is the best explainer thanks to him to make my weaker chapter to loved chapter!!!

[priyankapathak]

22:50
1) (D) 25
2) In case (i), 2 of the 3 resistors are to be connected in parallel and the third one to be in series with the first two.
In case (ii), 2 of the 3 resistors to be connected in series and the third one to be in parallel with both of them.

Am very happy that physics wallah started foundation channel.. 💕

[tonystark]

Before I don't understand this chapter
After watching the physics wallah lectures I love this chapter
Thank you so much sir

[vedanshmishra]

Sir the answer for the homework question 1 is d 25 because if we assume that a wire is cut into 5 equal parts the resistance of each part is equal to a .so when the each piece of wire is arranged in series the resistivity of the wire (R) will be a+a+a+a+a i.e. 5a
Now when the pieces are arranged in parallel the resistivity is(1/R' )=1/a+1/a+1/a+1/a+1/a
So our 1/R'= 5/a
So R'=a/5
Now ATQ, we have to fine the ratio of R /R'
So 5a/a/5= 25
So at last we can conclude that the ratio is 25/1
Therefore the correct option isD

Sir ji salute h apko Kya padhte h sir maza AA jata h...pure saaal smjh nhi aya electricity apne toh....chutikiyo me samjha diya....aisehi light v kra dijiye jldi

[surbhirawat]

22:28---> 1. (D) 25
2. (I) Two resistors in parallel and one in series with them.
(ii) Two resistors in series and one in parallel with them.

[sudhakarpandey]

The only channel which teaches each and every concept practically...resolves the concepts so well! 😊😊🙏

[primesentinel]

Previous years numerical:
1) d- 25 ohm
2) i) first two are connected in parallel and its equivalent resistor is connected in series
ii)first two are connected in series and its equivalent resistor is connected in parallel

[manjubala]

Thank you so much sir for this awesome watching your video...I am able to solve each nd every numerical related to combination of resistance.... Thank you so much 😊

[asmitakumari]

Ans1 25 (option D)
Ans2 .{1} - (two in parallel with one in series.)
{2}- (two in series with one in paralle)
