Question

two point situated 0.5 metre records have a potential difference of 50 volt find the magnitude of work required to take 2 coulomb of charge from one point of other ​

Answer 1

Answer...

• A current of 1 ampere means that there is 1 coulomb of charge passing through a cross section of a wire every 1 second.

• [1 ampere = 1 coulomb / 1 second]

• Note

• some extraneous information is given in each situation.

• A 2 mm long cross section of wire is isolated and 20 C of charge is determined to pass through it in 40 s.

• A 1 mm long cross section of wire is isolated and 2 C of charge is determined to pass through it in 0.5 s.

rules of the following...

• high current is the result of several coulombs of charge crossing over a cross section of a wire on a circuit.
