The current in a diode is given by the equation \(\mathrm{I}=\left(\mathrm{e}^{1000 \mathrm{~V} / \mathrm{T}}-1\right)\) where ' \(\mathrm{V}\) ' is applied voltage in volt and ' \(\mathrm{T}\) ' is absolute temperature in kelvin. A student measures the current as \(11 \mathrm{~mA}\) at \(300 \mathrm{~K}\). If the error in measuring voltage is \(\pm 0.01 \mathrm{~V}\), error in the value of current in \(\mathrm{mA}\) is
