“10th Class Physics Chapter 14 Quiz: Current Electricity” discusses the flow of electric charges in a circuit and the principles governing it. This chapter is very important for MDCAT students because it lays down the foundation of understanding electric circuits, resistance, and energy transfer, which are always tested in physics exams. Our MDCAT Quiz for this chapter helps students practice and excel in these essential concepts.
The chapter starts by defining electric current as the rate of flow of charge and introduces its unit, the ampere (A). Students will learn Ohm’s Law, which sets the relationship between voltage, current, and resistance in a circuit and is expressed as V = IR. The chapter further explores the concept of resistance and its factors—material, length, and cross-sectional area—how that affects current flow. Resistivity and conductivity are also discussed in detail. The major topics in this chapter are series and parallel circuits, their differences, and how to calculate equivalent resistance in each. This chapter also covers electric power, energy dissipation, and application of Kirchhoff’s Laws in solving complicated circuits.
