But let’s go back to: We can solve this series circuit for V2 : Rtot = 7 + 14.9833 = 21.9833Ω 14.9833Ω 9.6556 V 7Ω V2
But let’s go back to: We can solve this series circuit for V2 : Rtot = 7 + 14.9833 = 21.9833Ω I = V/R = 9.6556/21.9833 = .4392A 14.9833Ω 9.6556 V 7Ω V2

Now, just for fun, let’s look at the 14.9833Ω subcircuit 14.9833Ω 9.6556 V 7Ω V2
Now, just for fun, let’s look at the 14.9833Ω subcircuit Remember that it has a voltage of 6.5810V across it 14.9833Ω 9.6556 V 7Ω V2

We can find the current through the 31Ω resistor fairly simply: I = V/R = 6.5810/31 = .2123A A3 29Ω 31Ω 6.5810V
We can find the current through the 31 resistor fairly simply: I = V/R = 6.5810/31 = .2123A But this is not the only current running through the ammeter A3. A3 29Ω 31Ω 6.5810V
It also reads the current going through the 19Ω subcircuit A3 29Ω 31Ω 9.6556 V .2123A 7Ω V2 19Ω
It also reads the current going through the 19Ω subcircuit I 19Ω = V/R = 9.6556/19 = .5082A A3 29Ω 31Ω 9.6556 V .5082A .2123A 7Ω V2 19Ω
It also reads the current going through the 19Ω subcircuit I 19Ω = V/R = 9.6556/19 = .5082A So the reading on A3 is the sum of these currents: = .5082+.2123 = .7205A A3 29Ω 31Ω 9.6556 V .5082A .2123A 7Ω V2 19Ω
It also reads the current going through the 19Ω subcircuit I 19Ω = V/R = 9.6556/19 = .5082A So the reading on A3 is the sum of these currents: = .5082+.2123 = .7205A Ta Daa! A3 29Ω 31Ω 9.6556 V .5082A .2123A 7Ω V2 19Ω
