Solving
problems electric current,
Current is
flow of electric charge through a conductor but before we start solving
problems in electric current, let me
explain how to approach a general physics problem,
In solving problems
or questions in physics there are some parameters to consider.
1. To solve questions in physics 1st
of all is to identify what topics the word problem is from.
Is it under nuclear physics, quantum, electrodynamics or atomic physics
etc.
2. Identify all the parameters given in
the questions, and write them down
3. From the data you obtained from
questions deduce the formula that is best suitable for the question.
4. From the equation, sort out the term
that their value are already given and those that are not given.
5. For parameters in the formula with no
value , use any suitable equations to
find their value
6. Ensure that all data given are in
their S.I unit, or convert them before substituting them into the equation.
7. For formula with parameters having
constant values ensure that you have supplied the constant value and the must
be in their S.I units.
8. Apply the chosen formula and evaluate
the arithmetic until you solve it.
9. Ensure the value you substitute into
the equations are in the correct form, for example if you calculating masses in evolt don’t use the kilogram mass,
make the conversion before substituting.
10.
Ensure
you put the correct S.I unit to your answer.
