Calculate resistance of a parallel circuit
4 Ways to Calculate Total Resistance in Circuits - wikiHow
The calculated equivalent resistances for the series circuits will abide by the equation Req = R1 + R2 and for the parallel circuits the value will be similar to 1/Req = 1/R1 + 1/R2. The current flow is expected to be uniform throughout the series circuits, but will be stronger through the smaller resistor in …

For parallel circuits, since all the resistors are connected at the beginning and the end of the current paths it takes the same work for a charge to travel through any resistor. Since charge must be conserved, the total current must split, giving: i = i1 + i2 + i3 + i4 But for each resistor, V=iR, so,

E. Resistance of Parallel Circuits. 1. Draw two closely spaced, parallel lines of equal length, say 5-cm long and 5-mm wide. Measure and record the resistance of the first line (R1), then do the same with the second line (R2). 2. Now connect the ends of the two lines together and measure the resistance of the resulting parallel circuit (Rtotal). 3.

Form hypothesis: How do you think the total resistance of a parallel circuit is calculated? _____ Experiment: With the battery voltage set to 15 volts, measure the current in a parallel circuit with 1, 2, 3, and 4 light bulbs. (In each case, place the ammeter next to the battery.) Use Ohm’s law to calculate the total resistance of the circuit.
