@Koro Oh I see how it works. Thanks for saving my life again B-]

so it will eliminate the term $\frac{q_1q_1}{r_{11}}$ first time and then $\frac{q_2q_2}{r_{22}}$ at second time right?

MethNoob

Mar 6, 2022 10:31

Ok I will take time to digest it.

MethNoob

Mar 6, 2022 10:26

Sigma that inside is $\frac{q_iq_1}{r_{i1}}+\frac{q_iq_2}{r_{i2}}$

@Koro yeah I did that

Dot product also follows product rule.

MethNoob

Mar 6, 2022 03:57

@Koro no but now I see I proved it.

MethNoob

Mar 6, 2022 03:53

@Koro so they replaced dot product with product?

Ohm's law holds for circuits containing only resistive elements (no capacitances or inductances) for all forms of driving voltage or current, regardless of whether the driving voltage or current is constant (DC) or time-varying such as AC. At any instant of time Ohm's law is valid for such circuits.

MethNoob

Apr 7, 2022 15:23

Ohm's law

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship: I = V R , {\displaystyle I={\frac {V}{R}},} where I is the current through the conductor in units of amperes, V is the voltage measured across the conductor in units of volts, and R is the resistance...

Q: Why is electric field zero in a wire with 0 resistance given nonzero voltage?

Why is electric field zero in a wire with 0 resistance given nonzero voltage and infinite charge inside a battery? It is true that for a wire with $0$ resistance there will uniform voltage across the wire. But comparing with an electron in an empty space it seems to be different. Imagine in a spa...

I think I understand it now a bit may be I need to contemplate it for a bit thanks for help I will try to reread it again and think more carefully

MethNoob

Mar 10, 2022 16:16

Yes makes little sense.

MethNoob

Mar 10, 2022 16:15

Potential is 0 on negative and N V on positive terminal. Potential difference is NV. "So the voltage rise from the battery must equal the voltage drops from the capacitors" is little bit confusing.

MethNoob

Mar 10, 2022 16:11

Yeah I was thinking this.

MethNoob

Mar 10, 2022 16:09

Is it because potential energy changes because the charges moves?

MethNoob

Mar 10, 2022 16:07

Why?

MethNoob

Mar 10, 2022 16:07

So moving from positive to negative terminal voltage drops.

MethNoob

Mar 10, 2022 16:05

So set negative terminal of battery as 0V and positive as NV where N is real number.

MethNoob

Mar 10, 2022 16:04

I will try to sketch and think about it.

The one thing I only know is charge quantity is same on all the capacitors in series.

MethNoob

Mar 10, 2022 15:48

Why is the sum of the voltages of the capacitors in series equal to the voltage of the battery?
