How are voltage, current and resistance calculated in a parallel circuit? The voltage is the same across each device. The total current divides among the parallel branches. The total current is the sum of the currents in its branches. The reciprocal of the total resistance is equal to the sum of the reciprocals of individual resistance.
Resistors in parallel A parallel circuit is identified by the fact that it has more than one current path (branch) connected to a common voltage source.
- identify a parallel circuit and the current and voltage through each element in the parallel circuit. - calculate the equivalent or total resistance of a parallel resistivity circuit. - apply Kirchhoff’s Current Law, KCL, and Current Divider Rule, CDR, to find an unknown current in a parallel circuit.

Series-Parallel Circuits If we combined a series circuit with a parallel circuit we produce a Series-Parallel circuit. •R1 and R2 are in parallel and R3 is in series with R1 ǁ R2. The double lines between R1 and R2 is a symbol for parallel. We need to calculate R1 ǁ R2 first before adding R3.
Rules for analyzing series and parallel circuits apply: Same current occurs through all series elements Same voltage occurs across all parallel elements
6.4 PARALLEL CIRCUITS Simple Parallel circuit: and The voltage across parallel elements is the same: V 1 = V 2 = E and For single-source parallel networks, the source current (I s) is equal to the sum of the individual branch currents.
Components in parallel have their own separate circuit or loop. If resistor 1 in the diagram was removed this would only break that circuit, a current would still flow through resistors 2 and 3. The total current is equal to the sum of the currents through each resistor. The total potential difference is equal to the p.d.s across each resistor.
