Charge equation current time
WebPutting "charge is quantized" in terms of an equation, we say: q = n e q is the symbol used to represent charge, while n is a positive or negative integer, and e is the electronic charge, 1.60 x 10-19 Coulombs. The Law of Conservation of Charge. The Law of conservation of charge states that the net charge of an isolated system remains constant. WebCharge (Q) = Current (I) x Time (t) (Charge must be given in coulombs, current in amps and time in seconds) You may meet smaller currents than one amp in school. For these currents we use milliamps and microamps. 1 A = 1000 milliamp (mA) 1 A = 1 000 000 microamps ( m A)
