03.Current Electricity | NEET PHYSICS - AnkiDeckLib

This is a flash card deck for the chapter 'Current Electricity' of Class 12th, based on the latest syllabus for NEET 2024. You can download other chapters by clicking on "The author has shared x other item(s)." below the title of this page.

⚠️TIP: When studying for the first time, focus on learning instead of answering, and when the next time the same card shows up again, then try to answer, so that you know what kind of answer you have to give and understand the question better. Remember, your answer does not need to be theoretically identical to the real answer, answer it in your way and then revise the official answer while checking your own answer. It's Physics so mostly it's just formulas, this deck is best for repetitive revision of formulas, as that's the most important part in physics for NEET, but ofc this is not enough, a good amount of question practice is very important, flashcards can only help you in remembering formulas. I hope these flash cards will help you in your preparations. Best of Luck for your NEET exam, do you best👍🙏.

Sample Data

Text	Combination of resistance -1. Series - {{c1::Current (Ⅰ)}} is constant and {{c1::potential difference (V)}} is variable in series combination of resistance.Rs = {{c1::R1 + R2 + R3}} \| Rs = {{c1::nR}} (← for n identical resistance in series)2. Parallel - {{c1::Potential difference (V)}} is constant and {{c1::current (Ⅰ)}} is variable.{{c1:: ::Rp = ?}}(for n identical resistance in parallel) → {{c1:: }}

Personal Notes	Here, Rs and Rp means Req or Requivalent for Series and Parallel combination respectively.

Text	Galvanometer: Used to detect (measure) small current (in mA and μA) and its direction.G - Galvanometer resistance \| Ig - maximum current through galvanometer which gives full scale deflection.Galvanometer is very sensitive. Cannot be used to measure large current.Ammeter: used to measure large current. Moving coil galvanometer can be converted into a ammeter by {{c1::introducing a shunt resistance, of small value in parallel}}. Ammeter is always connected in {{c1::series}} in the circuit. {{c1::Voltage is same in parallel combination so, VG = VS ⇒ ⅠgG = (Ⅰ - Ⅰg)S, now we can write - ::Formula for Shunt(S)?}}Resistance of a Ideal Ammeter should be {{c1::zero}}.Voltmeter: It's always connected in {{c1::parallel}} to measure Potential difference.Galvanometer can be converted into a voltmeter by {{c1::introducing a resistance of a large value in series}}.Resistance of an Ideal Voltmeter should be {{c1::infinite}}.
Extra	Practically however small the shunt is, the Resistance of Ammeter is not exactly zero and Hence the current measured by Ammeter is lesser than the actual current.
