Voltage Coefficient of Resistance
Voltage coefficient of resistance, abbreviated as VC, is the change in resistance with applied voltage.
Voltage Coefficient of Resistance formula
\(\large{ VCR = \frac { 100 \; \left( R_1 \;-\; R_2 \right) }{ R_2 \; \left( V_1 \;-\; V_2 \right) } }\) |
Where:
Units | English | Metric |
\(\large{ VCR }\) = voltage coefficient of resistance | \(\large{\frac{V}{I}}\) | \(\large{\Omega}\) |
\(\large{ R_1 }\) = resistance at the rated voltage \( V_1 \) | \(\large{\frac{V}{I}}\) | \(\large{\Omega}\) |
\(\large{ R_2 }\) = resistance at 10% of rated voltage \( V_2 \) | \(\large{\frac{V}{I}}\) | \(\large{\Omega}\) |
