Dimensional of a physical quality are powers to which base qualities are raised to represent that quality.

Gaurav Seth 1 week, 3 days ago

Dimensions of a physical quantity are powers (exponents) to which base quantities are raised to represent that quantity. They are represented by square brackets around the quantity.

• Dimensions of the 7 base quantities are – Length [L], Mass [M], time [T], electric current [A], thermodynamic temperature [K], luminous intensity [cd] and amount of substance [mol].

Force = Mass x Acceleration = [M][L]/[T]2 = [MLT-2]

V=ir
The current flowing through the conducter is directly proportional to the potential difference across the ends of the conductor provided temperature and others physical quantities remain same..V=IR

Ohm’s Law

• Ohm’s law is named after the scientist Ohm who gave this law.
• According to the Ohm’s law current flowing through a conductor is directly ∝ to the potential difference applied between the ends of the conductor.
• This means if the potential difference applied at the ends increases then the current flowing through the conductor also increases and vice-versa.
• Mathematically
• Current flowing through the conductor I ∝ V where V is the potential difference applied at the ends of the conductor.
• Or I=(constant) V where constant = 1/R where R =resistance of the conductor
• => I=(1/R)V
• =>V=IR

Relative error is defined as the ratio of the absolute error of the measurement to the actual measurement. Using this method we can determine the magnitude of the absolute error in terms of the actual size of the measurement. If the true measurement of the object is not known, then the relative error can be found using the measured value. Relative error gives an indication of how good a measurement is relative to the size of the object being measured.

If x is the actual value of a quantity, x0 is the measured value of the quantity and Δx is the absolute error, then the relative error can be measured using the below formula.

Relative error = (x0-x)/x = (Δx)/x

An important note that relative errors are dimensionless. When writing relative errors it is usual to multiply the fractional error by 100 and express it as a percentage.
