Why are measured values different from calculated values?

Measurements is the actual figure of the given thing. Whereas calculation is made by using the measured figures and putting that into formula. Measurement is primarily stage whereas calculation is secondary. For example, to know the actual value of grains per kg.

Why are measured values of the resistors different from the nominal values?

The actual (measured) resistance will vary from the nominal value due to subtle mechanical and chemical differences that occur during manufacturing. The manufacturer specifies the maximum deviation from the nominal value as a ±percentage. This range of deviation is called the tolerance of the resistor family.

Why do you expect that the voltage is different across each resistor?

The same current flows through each part of a series circuit. Voltage applied to a series circuit is equal to the sum of the individual voltage drops. The voltage drop across a resistor in a series circuit is directly proportional to the size of the resistor. If the circuit is broken at any point, no current will flow.

Why does the measured value of resistance for the series parallel circuit not agree with the calculated value?

The resistance overall resistance of the circuit is less as compared with that when they when they are having to bell in series. As in case we are having people because in case of two bulbs, the resistance will be more, the current will be less and when less current will be passing through the city’s combination.

What is the difference between measured value and calculated value?

VERY SIMPLY, measured value requires conversation and calculated value requires a computer. Either is an estimate of real value, which can only be determined when “one side” and “the other side” make an exchange. (And remember, the exchange can involve anything – cash, time, a bartered object, bitcoin, etc.)

Why are simulation and calculations different?

Re: difference between the calculation by hand and simulatio Hand calculation takes simple mos model (level 1) into consideration. On the other hand computer simulation takes complex model into consideration,while doing calculation. Difference betn results are very less than 5 to 10 \%.

What is the difference between nominal value and face value?

Nominal value of a security, often referred to as face or par value, is its redemption price and is normally stated on the front of that security. For bonds, the nominal value is the face value, and will vary from its market value based on market interest rates..

What is the largest value the resistor can be and still be in tolerance?

517 K
Take the nominal value and multiply it by 1 + your tolerance, which is (1+0.1). Then take the nominal value and multiply it by 1 – tolerance, or (1-0.1). The highest possible value is 517 K.

Why is the voltage across resistors in parallel the same?

The voltage across parallel resistors is equal because they are all connected to the same two nodes in the circuit.

Does the resistance obtained from the plot of V against I is the same as resistance values of a resistor used in the circuit Explain your finding?

The phrase IR drop is often used for this voltage. If voltage is measured at various points in a circuit, it will be seen to increase at the voltage source and decrease at the resistor. In a true ohmic device, the same value of resistance will be calculated from R = V/I regardless of the value of the applied voltage V.

How to calculate the value of the resistor?

Stated value of the resistor can be calculated by it color coded value. Measured value will be between maximum and minimum value due to tolerance variation. Ex: 1K 5\% resistor measured value will be between 950 ohms and 1050 ohms.

Why does the value of a resistor change when connected in parallel?

When you connect the meter across the resistor, you are connecting the meter’s internal resistance in parallel with the resistor, and the results you see will actually be for the parallel combination ot As others have mentioned, the value of your resistor may differ from the stated value due to the expected tolerance of the particular resistor.

What determines the value of electrical current in a circuit?

There are two influences on the measured versus calculated (theoretical) values of electrical current. First is the tolerance of manufactured components. A resistor, for example, will have a tolerance specification in percent. Let’s say a resistor in a simple series circuit with 1V applied has a nominal value of 100 Ohms.

What is a tolerance rating for a resistor?

A resistor (and other electronic components) has a value tolerance that allows its actual value to deviate from its rated (stated) value by an amount specified by its tolerance rating. Some tolerance ratings are 10\%, 5\%, 1\% and 0.1\%.
