Question

Find the equivalent resistance between a and b. Also what is the current in the resistors?(7 resistors, 7 currents) V=24V over the circuit

Answer 1

Answer 2

please wait a moment, someone is calling me to the phone

Answer 3

First of all I have just collected all the resistors and found out that\[R _{tot}=11.1 \Omega\]

\[I=\frac{ V }{ R } >I=\frac{ 24V }{ 11.1\Omega }=2.2Ampere\]

Answer 4

then I have trouble to make kirchoff's second principle around the circuit to get the currents through the resistors..

Answer 5

Its allright, take your time:)

Answer 6

here I'm

Answer 7

I think that the requested resistance, is the resistance of the equivalent circuit

Answer 8

so Rtot is almost 2.3ohm?

Answer 9

and:
\[\Large \frac{1}{{{R_{{\text{eq}}}}}} = \frac{5}{{28}} + \frac{2}{{11}}\]

Answer 10

I got:
R_eq=2.77 ohm

Answer 11

when it is possible, is better to apply the Ohm's law, rather than the second Kirchhof's law

Answer 12

now, it is easy to compute the currents, which flow into the resistors

Answer 13

so I=8.6 ampere
