A current of 4A flows around a circuit for 10s. How much charge flows past a point in the circuit in this time?

How much current must there be in a circuit if 100 coulombs flow past a point in the circuit in 4 seconds?

An electric heater is connected to the 230V mains supply. A current of 8A flows through the heater. (a) How much charge flows around the circuit each second? (b) How much energy is transferred to the heater each second?

The rate of flow of charge in a circuit is called electric current. In other words, it is the amount of charge flowing per second. It is denoted by the letter I. If Q is the charge which is flowing through a conductor in time t, then current is given by i = Q/t Unit of current: The S.I unit of current is ampere and it is denoted by the letter 'A'. The S.I unit of Q is coulomb and that oft is second. Thus, the S.I unit of electric current is ("1coulomb")/("1 second") = 1A How much current must there be in a circuit if 100 coulombs flow past a point in the circuit in 4 seconds?

How much time is required for 10 Coulombs of charge to flow past a point if the current is 2 amperes?

How much time is required for 10 Coulombs of charge to flow past a point if the current is 2 amperes?

Total current flowing through the circuit:

An electric current of 6 A flows through a circuit for 10 minutes. Write the following steps in sequential order to find the electrons that would pass through the circuit in 10 minutes. Note the given data about current (i) and time (t). The number of electrons (n) flowing through the circuit can be found using, Q = ne (2) (c) Find the charge (Q) that flows through the circuit using , Q = it (1) (d) Equate (1) and (2), to find n.
