I-V analysis of an electrical circuit in the NI Multisim application is carried out by building a circuit scheme with the circt composition, namely resistance, voltage source and using voltage measuring instruments and current measurit instruments which are all arranged in such a way by referring to electrical circuit theory. Thus, the subject of this researc is the series-parallel circuit scheme and Khirchoff's law which carry out calculations, measurements and simulations 1 obtain current and voltage.

In table | the values for each resistance are R2 = 1.50, R3 = 2.7 O, R4 = 3.3 Q, R7 = 1.5 ©, R8 = 1.2 Q. The current value for each resistance which is connected in a mixed manner can be seen that the practical and theoretical values have an error value of 0% to 24.24% respectively located at R3 at the 6V voltage source and R2 at 12V. After knowing the Current and Voltage analysis in each circuit, whether Series, Parallel and Series-Parallel or mixed, you can then analyze the circuit based on Khirchoff's law. Measurements of the current flowing in each circuit have been carried out based on the circuit kit module and with the NI Multisim application which can be seen in figure 3.2

In principle, Khirchoff's law states that at any time, the algebraic sum of the stresses in a loop is zero, so you must pay attention to the sign of the stress in the loop equation. Apart from that, this law has the same principle as energy conservation, namely the energy provided by the source is the same as the energy absorbed by the load. Khirchoff's law is also a circuit requirement, while the I-V characteristics of an element are an element requirement. Based on table 4.5, it can be seen that the current in |; is the same as the sum of the current in |, and the current in |, for each specified voltage variation. The measurement values with the Khirchoff kit module are different from the NI Multisim simulation, but the differences are still relatively small, ranging from 6% to 28%. In Khirchoff's law, the incoming current is the same as the outgoing current. This is proven in the data obtained both in measurements and in simulations with the NI Multisim application.
