### What happens when resistors are connected in series and in parallel?

In brief, the overall or net resistance changes and the resistors in series and/or parallel can be represented by a single equivalent resistor. If you consider series resistors the equivalent resistance of the series would be: R = R1+R2+ ... +Rx The equivalent resistance of parallel resistors would be: 1/R = 1/R1 + 1/R2 + ... + 1/Rx One rule to always remember when dealing with series and parallel resistors is the voltage across each…

### How do you measure current and voltage in circuit by kirchoff's method?

Kirchhoff (not 'Kirchoff') doesn't suggest any way of measuring current or voltage in a circuit. Kirchhoff's Voltage Law defines the relationships between potential differences around any closed loop within a circuit. Kirchhoff's Current Law defines the relationships between currents at any junction within a circuit. Kirchhoff's Laws may also be used to solve complex circuits ('complex' circuits are those circuits which are not series, parallel, or series-parallel). Current and voltage may be measured with an…

### Why kirchhofs is use parallel in circuit?

Note about the spelling: Kirchhoff has a double "f". Basically, Kirhhoff's Laws are valid under a wide variety of situations. Specifically, you can use them in both parallel and series circuits, and in more complicated cases (such as multiple current loops). In the case of parallel circuits: Kirchhoff's Voltage Law tells us that the voltage between the two endpoints is the same, no matter what route is taken. Kirchhoff's Current Law tells us that the…
