Study Notes
Formulae and Units
- The percentage discrepancy formula is ((M - V) / V) × 100, where M is the measured value and V is the true value.
Representation of Measurements
- When measuring the radius of a wheel, the correct representation of the diameter is 2 × (measured radius) = 2 × 4.16 cm = 8.32 cm.
Coulomb's Law
- The base SI units of Coulomb's constant (k) are N m² C⁻².
Electric Units
- Volts (V) can be expressed in terms of base SI units as kg m² s⁻³ A⁻¹.
Capacitance
- Capacitance (C) is expressed in terms of charge (Q) and potential difference (V) as C = Q / V.
