Study Notes
Electric Circuits
- The unit of electric current is ampere (A).
- The unit of potential or voltage is volt (V).
Electric Potential
- The formula for potential difference is V = W / Q, where V is the potential difference, W is the work done, and Q is the charge.
- The capacity of a charged body to do work is called electric potential.
Electric Current
- The formula for electric current is I = Q / t, where I is the electric current, Q is the charge, and t is the time.
- The symbol 'I' in the equation I = Q / t represents electric current.
- The unit of potential difference is volt (V).
Electromotive Force
- The force required to move an electron from the negative to the positive terminal of a battery is called electromotive force (EMF).
- The difference of electrical potential between two charged bodies is called electric potential difference.
Note: EMF and electric potential difference are often referred to as voltage, but technically, EMF is the "pressure" that drives the flow of electrons, while electric potential difference is the "pressure difference" between two points.
