One coulomb of charge passes through a point in an electric circuit every ten seconds. What is the current of the circuit?
current=charge/time=1/10=.1Amp
To find the current of the circuit, you need to use Ohm's law, which states that the current (I) is equal to the amount of charge (Q) passing through a point in the circuit divided by the time (t) taken for the charge to pass through that point. The formula for current can be written as:
I = Q / t
In this case, you are given that one coulomb of charge (Q) passes through a point in the circuit every ten seconds (t). Plugging these values into the formula:
I = 1 coulomb / 10 seconds
Therefore, the current of the circuit is 0.1 amperes (A), since 1 coulomb is equal to 1 ampere-second (A·s).
To find the current, you simply divide the amount of charge (in coulombs) by the time (in seconds) it takes for that charge to pass through the point in the circuit.
