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?
Calculate the current in a wire if 1500 C charge is passed through it in 5 minutes.
If a current of 10 mA passed through your cell phone battery charger wire for 10 minute , what quantity of electric charge is transferred through the wire to the battery?
If a current of 10 mA passed through your cell phone battery charger wire for 10 minute, what quantity of electric charge is transferred through the wire to the battery?
If a current of 10 mA passed through your cell phone battery charger wire for 10 minute, what quantity of electric charge is transferred through the wire to the battery?
Calculate the electric current through a wire if 10 coulombs of charge flow through a cross section of the wire in 2 seconds.
20 mu A current flows for 30 seconds in a wire, transfer of charge will be
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?
