V= 9 Valts
Calculate the circuit
For the above circuit, say R1 = 10 N on the main line. R2 = 20 N and R3 =
100 Ω.
1) Since R2 and R3 are in parallel, we can use equation (3) to calculate the
equivalent total resistor R23 .
2) After that since R1 and R23 are in series, we can use equation (2) to
calculate the overall total RT.
3) The battery V=9 volts is known, Ohm's can be applied to RT, total current
can be calculated, and the total current is equal to I1
4) With I, and R1, Ohm's law can help us to get V1
5) V1 +V½ (or V3) = 9 volts, we get V2
6) Again, use Ohm's to get I2 and I3. The circuit is solved.
