Question

Find the current through the battery in the circuit shown in the figure .
Find the current through the resistor R1, R2, R3, and R4 in the circuit.

Will attach figure. Please help.

Answer 1

The current should be the 14.0 Volts it has listed as the first number.
I am not too sure about the resistors. I mean, on a guess, since the R1 and R3 add up to equal the 2.00 for R2 and the R4 = R5 being 1.00 maybe add both 2.00 + 1.00 to get 3.00 as the resistor. But then again I'm not sure, you would have to get someone much smarter on this type of thing.

Answer 2

Hi sjone103!

You have to use any technique such as mesh analysis, kirchoff's law or nodal analysis etc. or you can also use theorem like norton's theorem or thevenien's theorem.

Otherwise you can't solve it.

Answer 3

To use Kirchhoff's law, choose 3 loop-currents as the ones on the attached picture and writes 3 equations, then solve for \(i_1\), \(i_2\) and \(i_3\).

Equation for loop 1 would be: \(E=14=R_1(i_1-i_2)+R_2(i_1-i_3)\)
Write down the other equations.
