A current of 3A flows through a conductor for 4s. What amount of charge passes through the conductor? |
|
Answer» Answer: There is a relationship between CURRENT and charge. The relationship is as shown below: Charge (Q) – charge is measured in coulombs (C). Current (I) – is measured in amperes (A). Current is the rate of flow of charge. A current of 1 A MEANS that 1 coulomb of charge flows past a point in a circuit every second. ( 1 A = 1 C s-1 ) Current is measured in a circuit using an ammeter which is placed in series with the component of INTEREST in the circuit. Where current is equal to the CHANGE in charge over change in time I=∆Q/∆t From your question . How much charge? This is Q=It Therefore, 2x3=6 Coulombs |
