If 20 Coulombs of charge passes a point in a circuit in 1 second, what is the value of the current flowing?
20 Ampere
1 A = 1 C/s Therefore, our calculated value of 20 C/s is equal to 20 Amperes. I = 20 A Comparing with Options The calculated current is 20 Ampere.
Solar energy is converted into electric energy through
The work done in moving a charge of 2 coulomb (C) from point A to point B is 24 J. What is the potential difference between A and B?
Two conducting wires of the same material and of equal lengths and equal diameters are first connected in parallel and then in series in a circuit across the same potential difference. The ratio of heat produced in parallel and series combinations is
Direction of flow of electric current is from
