# what is kirchhoff’s loop law

## Best answer

Kirchhoff鈥檚 loop rule states that the sum of all the electric potential differences around a loop is zero. It is also sometimes called Kirchhoff鈥檚 voltage law or Kirchhoff鈥檚 second law. This means that the energy supplied by the battery is used up by all the other components in a loop,since energy can鈥檛 enter or leave a closed circuit.

### What is Kirchhoff鈥檚 voltage law for single circuit loop?

A Single Circuit Loop. Kirchhoff鈥檚 voltage law states that the algebraic sum of the potential differences in any loop must be equal to zero as: 危V = 0. Since the two resistors, R1 and R2 are wired together in a series connection, they are both part of the same loop so the same current must flow through each resistor.

### What is Kirchhoff鈥檚 Loop?

Kirchhoff鈥檚 Circuit Loop. That is 危V = 0 The theory behind Kirchhoff鈥檚 second law is also known as the law of conservation of voltage, and this is particularly useful for us when dealing with series circuits, as series circuits also act as voltage dividers and the voltage divider circuit is an important application of many series circuits.

### What is Kirchhoff鈥檚 second law?

Kirchhoff鈥檚 Second Law. According to Kirchhoff鈥檚 voltage law, the voltage around a loop equals to the sum of every voltage drop in the same loop for any closed network and also equals to zero.

### What is the loop rule in Kirchhoff second rule?

Kirchhoff鈥檚 Second Rule. Kirchhoff鈥檚 second rule (the loop rule) is an application of conservation of energy. The loop rule is stated in terms of potential, V, rather than potential energy, but the two are related since PE elec = qV. Recall that emf is the potential difference of a source when no current is flowing.
