विद्युत धारा
In this Class 10 Science topic from the chapter Electricity, students learn how electric charge flows through a conductor and what is meant by electric current. They explore its conventional direction, SI unit (ampere), and measurement using an ammeter. The topic also connects current with potential difference and resistance, helping students understand simple electric circuits, apply the relation between these quantities, and interpret everyday uses of electricity safely and scientifically.

Up to 1 questions from this page. Select your focus, then start.
The SI unit of electric current is ampere (A). Current is the rate of flow of electric charge through a cross-section of a conductor: \(I=Q/t\). Volt is the unit of potential difference, ohm is the unit of resistance, and watt is the unit of electric power. Exam tip: remember A for current, V for potential difference, and \(\Omega\) for resistance.
