10TH PHYSICS* ELECTRICITY* POTENTIAL & POTENTIAL DIFFERENCE* తెలుగు /English

Learn electric potential, potential difference, resistance, EMF and internal resistance through clear explanations, circuit diagrams and numerical examples. This detailed physics lesson explains the meaning of electric potential and potential difference, how voltage moves electric charge through a circuit and how electrical quantities such as current, voltage and resistance are related. Electric potential difference between two points is defined as the work done per unit charge in moving a charge from one point to another. The video explains this concept using the formula: V = W/Q where V is the potential difference, W is the work done and Q is the electric charge. Topics covered in this video: • Meaning of electric potential • Meaning of potential difference • Work done in moving an electric charge • Formula for potential difference: V = W/Q • SI unit of potential difference • Meaning of one volt • Difference between electric potential and potential difference • Measuring voltage using a voltmeter • Correct connection of a voltmeter in parallel • Measuring electric current using an ammeter • Correct connection of an ammeter in series • Understanding basic electrical circuit diagrams • Resistance offered by a conductor • Conductors, resistors and resistance • Ohm’s law: V = IR • Relationship between voltage, current and resistance • SI unit of resistance: ohm • Meaning of one ohm • Factors affecting the resistance of a conductor • Effect of conductor length on resistance • Effect of cross-sectional area on resistance • Potential difference and current numerical problems • Cells and electromotive force • Meaning of EMF • Internal resistance of a cell • Terminal potential difference • Current through a cell with internal resistance • Application of the circuit-loop rule • Formula: I = ε/(R + r) • Electrolytic cells and potential difference The lesson also explains how to identify the correct positions of an ammeter and voltmeter in a circuit. An ammeter is connected in series to measure current, while a voltmeter is connected in parallel across the component whose potential difference is being measured. Through worked examples, students can understand how changing the applied voltage affects current when resistance remains constant. The video also introduces the difference between the EMF of a cell and its terminal potential difference when current flows through the circuit. This lesson is useful for Class 10 students, intermediate physics learners and anyone studying current electricity. It is ideal for conceptual understanding, examination revision and numerical-problem practice.
