Can you combine parallel circuits?
By repeating steps 1 and 2, you can continually reduce the circuit until only a single equivalent resistor remains. Then you can determine the total circuit current. The voltage drops and currents though individual resistors can then be calculated.
Why do parallel circuits have more current?
In a parallel circuit, the potential difference across each of the resistors that make up the circuit is the same. This leads to a higher current flowing through each resistor and subsequently the total current flowing through all the resistors is higher.
Can a circuit be a combination of series and parallel?
Because the circuit is a combination of both series and parallel, we cannot apply the rules for voltage, current, and resistance “across the table” to begin analysis like we could when the circuits were one way or the other.
How is the current of a parallel circuit determined?
There are three values left to be determined – the current in each of the individual resistors. Ohm’s law is used once more to determine the current values for each resistor – it is simply the voltage drop across each resistor (60 Volts) divided by the resistance of each resistor (given in the problem statement).
Can you combine resistors in series and parallel?
You can also combine resistors in parallel to create equivalent resistances. However, calculating the total resistance for resistors in parallel is a bit more complicated than calculating the resistance for resistors in series. When you combine two resistors in parallel, current can flow through both resistors at the same time.
There are three distinct paths that current can take before returning to the battery, and the associated resistors are said to be in parallel. Where series components all have equal currents running through them, parallel components all have the same voltage drop across them — series:current::parallel:voltage. From there we can mix and match.
