We studied the broadband X-ray spectra of {\it Swift}/BAT selectedlow-accreting AGNs using the observations from {\it XMM-Newton}, {\it Swift},and {\it NuSTAR} in the energy range of $0.5-150$~keV. Our sample consists of30 AGNs with Eddington ratio, $\lambda_{\rm Edd}<10^{-3}$. We extracted severalcoronal parameters from the spectral modelling, such as the photon index, hotelectron plasma temperature, cutoff energy, and optical depth. We testedwhether there exists any correlation/anti-correlation among different spectralparameters. We observe that the relation of hot electron temperature with thecutoff energy in the low accretion domain is similar to what is observed in thehigh accretion domain. We did not observe any correlation between the Eddingtonratio and the photon index. We studied the compactness-temperature diagram andfound that the cooling process for extremely low-accreting AGNs is complex. Thejet luminosity is calculated from the radio flux, and observed to be related tothe bolometric luminosity as $L_{\rm jet} \propto L_{\rm bol}^{0.7}$, which isconsistent with the standard radio-X-ray correlation.
