One of learning methods to increase students understanding is Inquiry-based Learning (IBL) that places students’ questions, ideas, and observations as the center of learning. In this method, students worked in a group to learn through a process of inquiry by a stimulus question from the lecturer. In this paper, the IBL method was used to improve understanding in null-type measurement by using bridge circuit as a variable conversion to determine the level of water and its application. In this method, a group of three students was to inquire the topic. There are six steps that has been done: (i). stimulation, a stimulus question from a teacher, (ii). problem statement, driving questions to be solved and to make hypotheses, (iii). data collection, searching information and doing experiments, (iv). data processing, analyzing the data, (v). verification, making sure the students have solved their equations, and (vi). conclusion, answering the questions and presenting the result of enquiry. Following the IBL method, it was shown that the null-type D.C. bridge circuit with an LDR (light dependent resistor) as a sensor can be used to measure water level for anticipating flood.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Inquiry based learning (IBL),Inquiry-based learning,ITS applications,Light dependent resistor,Null type,Problem statement,Quality of education,Teaching methods[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Inquiry-based learning,LDR,Null-type Bridge,Water Level[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/1742-6596/1204/1/012080[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
