The question appears to be describing three resistors all in parallel.
The reciprocal of their net effective resistance is
(1/20) + (1/20) + (1/10) = (2/20) + (1/10) = (1/10) + (1/10) = (2/10) = 1/5.
The net effective resistance is [ 1 / (1/5) ] = 5 ohms.
There are three disadvantages of parallel circuits. These include the fact that they have complex resistance, voltage that is limited, and a current that varies.
The potential difference remains the same over the components in parallel and the current splits up proportianally to the components conductances. The components conductances add up to give the combined conductance of the parallel circuit. Conductance is 1 / resistance
5 ohms
There are three disadvantages of parallel circuits. These include the fact that they have complex resistance, voltage that is limited, and a current that varies.
Three resistors in parallel: 20 ohms, 20 ohms, 10 ohms.1/ total resistance = (1/10) + (1/20) + (1/20) = (2/20) + (1/20) + (1/20) = 4/20 = 1/5 mho.Total resistance = 5 ohms
In a parallel circuit, the total resistance is calculated as the reciprocal of the sum of the reciprocals of each individual resistance. So, for three resistances of 20 ohms, 20 ohms, and 10 ohms, the total resistance will be 1 / (1/20 + 1/20 + 1/10) = 1 / (0.05 + 0.05 + 0.1) = 1 / 0.2 = 5 ohms.
there are three types of circuits. Series,parallel,parallel-series. Series circuits usually are involved with dimming lights, and blown fuses.
The total resistance is 5 ohms. Scroll down to related links and look at "Parallel Resistance Calculator".
A simple circuit has three resistors connected in series. The resistors are 14 ohms 12 ohms and 9 ohms. What is the total resistance of the circuit?
The resistance of a series circuit is simply the sum of the individual resistors.
Ohm's Law says! R=V/I Resistance is directly proportional to Voltage. In series circuit, due to adding the resistance, total voltage will be increased, due to increasing of total voltage, total resistance of the series also be increased.
the three types of circuits are series, parallel, and series-parallel.AnswerThere are, in fact, four types or categories of circuit, not three! These are series, parallel, series-parallel, and complex.The term 'complex' is somewhat misleading, because a 'complex circuit' is not necessarily complicated (although they often are!) but merely the collective name for any circuit that isn't series, parallel, or series-parallel. A simple example of a complex circuit is a bridge circuit, such as Wheatstone's Bridge.
