Why the measured voltage might not be the same as the predicted voltage?
The voltage variation may be because of making a note of the wrong reading. For example, you note 10 volts theoretically, but it is only 9.3 volts under load. In an analog ammeter, there is a parallax error in reading the meter which pitches off the main measurement. There might be a loose connection.
Why doesn t your calculated resistance equal your measured resistance?
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 calculated and measured values differ with each other?
The equipment used to measure affects the measurement good quality affects less than bad quality. The measures may have been done under different conditions to the calculation . The parts used to construct the physical circuit have tolerances which may not have been accounted for in the calculation.
Why does the measured value of resistance for the series parallel circuit not agree with the calculated value?
AI Recommended Answer: 1) Resistance is measured in ohms, which is a measure of electrical resistance. Resistance in a circuit is affected by the amount of current flowing through it. Resistance in a series circuit is higher than in a parallel circuit because there is a shorter path for current to flow.
