2. Resistors: Restrict the flow of current; measured in ohms (Ω) 3. Conductive Paths: Allow current to flow through the circuit. II. Ohm’s Law and Calculating Current. A. Ohm’s Law Formula. Ohm’s Law states that the current (I) in a conductor equals the voltage (V) across it divided by its resistance (R). The formula is I = V/R.
Current is the rate at which electric charge flows past a point in a circuit. It is analogous to the flow rate of water in a pipe. Resistance is a measure of how much a component or material resists the flow of electric current. Higher resistance means less current for a given voltage.

The concept of electrical current was developed in the 18th and 19th centuries as scientists began to understand electricity more fully. The unit of current, the ampere (A), is named after André-Marie Ampère, one of the main discoverers of electromagnetism. Calculation Formula. The basic formula to calculate electrical current is:
A current of 1 ampere means 1 Coulomb of charge flows per second. The size of the electric current is the rate of flow of electrical charge. Calculating Charge Flow. The equation for calculating charge flow: Charge flow (in coulombs) = Current (in amperes) × Time (in seconds).
Electric current is measured in amperes, also known as "amps." One amp is a flow rate equal to one Coulomb per second. Thus, an electrical outlet emitting one amp of electricity actually has about ...
