What is the current through a wire if 240 coulombs of charge pass through the wire in 2.0 minutes?
2 answers:
Answer : Current flowing, I = 2 Ampere
Explanation :
It is given that,
Charge passing through a wire, q = 240 coulombs
Time taken to pass the charge, t = 2 minutes = 120 seconds
Electric current is defined as the ratio of the electric charge divided by time taken to pass the charge.
Mathematically, it can be written as :
Putting the value of q and t we get:
I = 2 Ampere
So, the current passing through the wire is 2 Amps.
Hence, this is the required solution.

✠ This question says that there is an object and its mass is 2 kg ; it's raised to a height 10 m and possess potential energy of 200 J. Now this question ask us to find the kinetic energy and the potential energy at a height 4 metre.
✰ Mass = 2 kilograms
✰ Raised height = 10 metres
✰ Posses potential energy = 200 Joules
✰ Kinetic energy at a height 4 metre
✰ Potential energy at a height 4 metre
✰ Kinetic energy at a height 4 metre = 120 J
✰ Potential energy at a height 4 metre = 80 J
✰ Potential energy formula.
✰ Potential energy = mgh
✰ Potential energy as P.E
✰ Mass as m
✰ Joules as J
✰ Height as h
✰ Raised height as g
↦ Potential energy = mgh
↦ Potential energy = 2 × 10 × 4
↦ Potential energy = 20 × 4
↦ Potential energy = 80 J
<h3>✠ Now according to the question let us find the kinetic energy</h3>↦ Kinetic energy = Posses potential energy - Finded potential energy
↦ Kinetic energy = 200 J - 80 J
↦ Kinetic energy = 120 Joules
