Equivalent resistance complex resistor circuit problems. Next we would proceed to calculate the parallel equivalent of that resistance r 2 r 3 r 4 with r 5 then in series with r 7 then in parallel with r 6 then in series with r 1 to give us a grand total resistance for the circuit as a whole. Draw the straight ie. Analyzing a resistor circuit with two batteries.

All through the branch geb current is i 3. The method of calculating the circuits equivalent resistance is the same as that for any individual series or parallel circuit and hopefully we now know that resistors in series carry exactly the same current and that resistors in parallel have exactly the same voltage across them. Let us analyse a simple circuit shown in the figure alongside.

Th all through the branch gfdab current in i 1. The first step is to simplify the circuit by replacing the two parallel resistors with a single resistor with an equivalent resistance. Solved examples of comlicated circuits illustration.

The equivalent resistance of a 4 w and 6 w resistor placed in parallel can be determined using the usual formula for equivalent resistance of parallel branches. Now draw resistor 3 and resistor 5 from points 3 and 4 respectively to point 5. Determine the following quantities for each of the two circuits shown below.

To analyze an rc or lr circuit more complex than simple series convert the circuit into a thevenin equivalent by treating the reactive component capacitor or inductor as the load and reducing everything else to an equivalent circuit of one voltage source and one series resistor. Assume current values i 1 i 2 i 3 at random directions. Without any curve between two points.

Our mission is to provide a free world class education to anyone anywhere. The equivalent resistance the total current from the power supply the current through each resistor the voltage drop across each resistor and. Now point 1 resembles point a and point 5 resembles point b as no resistor is placed between point a and point 1 and between point b and point 5.

Resistor circuits that combine series and parallel resistors networks together are generally known as resistor combination or mixed resistor circuits. We then apply ohms law to this simple or rather simplified circuit and.
