Conclusion :




        As for the conclusion for all 3 experiments that our group has done,we know how to use
multimeters in experiment 1 and experiment 2 that is categorize in two type,analog multimeter
and digital multimeter.Multimeter is a device that can be used to measured some component
such as resistor,capacitor,inductor and many more.Besides that,the used of multimeter including
in measuring resistance,current and voltage.In accuracy for those two type of
multimeters,analog multimeter and digital multimeter,digital multimeter is more accurate than the
analog multimeter.This was because analog multimeter use scale reading that has some errors
when we read the readings whereas digital multimeter use digital numbers that show us the
accurate readings.In experiment 3,our group was asked to used RLC meter to measure the
value three types of electrical component,resistor,capacitor and inductor.RLC meter can only be
used to measure this type of electrical component,it cannot measure the current and voltage in
a circuit.

        In all the experiment,we also know that there was two type of circuit,series and parallel
circuit.In series circuit,the current is the same for all components, IT =I1=I2=I3 but the voltage at
each components is different from each other.The sum of the voltage drop is same as the
voltage source,Vs=VR1+VR2+VR3.Resistance in series circuit can be calculate by adding all
resistors value,RT=R1+R2+R3.Whereas,in parallel circuit,the current is differ from the series
circuit,the current in parallel circuit that enter a point,is same as the sum of the current
out,IT=I1+I2+I3.The sum of voltage drop is same as the voltage source,Vs=VR1+VR2+VR3.The
resistance can be calculate as 1/RT=1/R1+1/R2+1/R3.For two resistors,we can use formula
R1xR2
     /R1+R2.

        In the experiment,we used multimeter to measure the value of current,resistance and
voltage drop.When we measure current,the multimeter is in series with the component.For
measuring voltage drop,the multimeter is parallel with the component.
