Individual resistances r 1 8kω r 2 2kω r 3 10kω. The construction of a series circuit is simpler. A effective resistance b current through the circuit c voltage across each resistor.
However we cannot take the value of 9 volts and divide it by 3k 10k or 5k ω to try to find a current value because we don t.
I frac v r s frac 9 v 90 omega 0 1 a. In such circuits the voltage across each resistor is different. R s r 1 r 2 r 3. In the three resistor example circuit below we know that we have 9 volts between points 1 and 4 which is the amount of electromotive force driving the current through the series combination of r 1 r 2 and r 3.
