Question Bank Electric Circuits, Resistance and Ohm s Law 1. Define the term current and state its SI unit. Ans. The rate of flow of charge in an electric circuit is called current. Its SI unit is ampere. 2. (a) Define Ampere. (b) Calculate the current flowing in ampere, if a charge of 5000 C flows through a circuit in 20 minutes. Ans. (a) When one coulomb of charge flows through a conductor in one second, then the current flowing through the circuit is said to be one ampere. (b) Current (I) = Q 5000 C 5000 C = = = 4.16 A t 20 min 1200 s 3. Define the term potential. State its SI unit. Ans. The amount of work done (energy spent) in moving a unit positive charge from infinity to a given point in an electric field is called electric potential. The SI unit of electric potential is volt (V). 4. (a) Define Volt. (b) 4000 J of work is done in bringing 1600 C of charge from infinity to a given point A in an electric field. Calculate the potential at point A. Class-X 1 Question Bank
