Resistor circuits that combine series and parallel resistors networks together are generally known as mixed resistor circuits. The method of calculating the circuit is similar to this example: In the following circuit we need first to calculate the total current (IT) taken from the 12v supply. At first glance this may seem a difficult task, but if we look a little closer we can see that the two resistors, R2 and R3 are actually both connected together in a “SERIES” combination so we can add them together to produce an equivalent resistance the same as we did in the series resistor tutorial. The resultant resistance for this combination would therefore be: R A =R2 + R3=8 Ω+ 4 Ω=12 Ω So we can replace both resistors R2 and R3 above with a single resistor of resistance value 12 Ω So our circuit now has a single resistor RA in “PARALLEL” with the resistor R4. Using our resistors in parallel equation we can reduce this
