      The electric current which flows into any junction in an electric circuit is equal to the current which flows out. Current Divider Rule For two parallel resistors, R 1 and R2, the current through the branch equals the resistance of the opposite branch times the input current divided by the sum of the two resistors.

      where I is the current strength (A), Q = charge (C) and t = time (s). Example 1: Calculate the current strength when 5 C of charge passes a given point in 2 s. Example 2: Calculate the quantity of charge passing a point in a circuit when a current of 5 A flows for 10 s. Q = It = 5 x 10 = 50 C. The formula Q = It can be used to define a Coulomb.

      The electric current I in the wire is defined as: The units of electric current are C/s (coulombs per second). *1 C/s is defined as one ampere (or one amp) (A): 1 C/s = 1 A. The ampere is named after the French mathematician André-Marie Ampère (1775 – 1836). If the current is constant in time it is called direct current (DC).

      Current (I) – the rate at which charge pass through a wire. Units = C/s = Amperes (A) Although many practical applications and devices are based on the principles of static electricity, electricity did not become an integral part of our daily lives until scientists learned to control the movement of electric charge, known as current.

      Electric Potential (Voltage): To find the electric potential of a power supply, you take the work supplied and divide it by the magnitude of the charge. Voltage (V) = Work V = work 1 volt = 1 joule/coulomb. Charge Q. Electric Current: Electric current is the measure of the flow of charged particles.
