This book looks into the Direct Current Resistivity Method and Induced Polarization (IP) techniques, essential for geophysical exploration. Covering both theoretical foundations and practical applications, it explores subsurface imaging, inversion modeling, and real-world case studies in mineral exploration, groundwater detection, and environmental studies. With depth discussions on electrode configurations, resistivity sounding, self-potential methods, and mathematical modeling, this book serves as a valuable resource for geophysicists, researchers, and professionals seeking advanced insights into electrical geophysics.
