Current Circuit Formula. The s i unit of current is called ampere a coulomb second. A total voltage of 2 5v is applied to the circuit.
Compute for the total current of the circuit. Resistive captative and inductive circuit already mentioned above. In direct current the charges flow in one direction but in alternating current the charges flow in both the direction.
Rtotal r 1 r 2.
If a charge q flows through the circuit for time t then i q t. The s i unit of current is called ampere a coulomb second. 1 ampere 6 25 10 8 electrons sec in metallic conductors the current is due to the motion electrons whereas in electrolytes and ionized gases both electrons and positive ions move in opposite direction. When a series connection of a resistor and an inductor an rl circuit is connected to a voltage source the time variation of the current is i i0 1 e t τ turning on where i0 v r is the final current.
