Answer: decreasing
An RC circuit is an electrical circuit composed of resistors and capacitors, where the charging time [tex]T[/tex] of the circuit is proportional to the magnitude of the electrical resistance [tex]R[/tex] and the capacity [tex]C[/tex] of the capacitor.
As shown below:
[tex]T=R.C[/tex]
In this context, the electrical resistance is the opposition to the flow of electrons when moving through a conductor.
Therefore:
When a capacitor is being charged in an RC circuit, the current flowing through a resistor decreases.
And the correct option is b.
RC circuit has both resistor and capacitor. The current in an RC circuit decreases with time.
What is an RC circuit?
An RC circuit is a circuit that consists of both a resistor and a capacitor.
As given to us that the current is flowing through an RC circuit, therefore, as the voltage in the capacitor reaches equal to the voltage of the source, the current in the circuit reduces.
The value of the current at the initial can be calculated as,
I₀=emf/R
When the voltage at the source is equal to the voltage in the capacitor, the current becomes zero.
Hence, the current in an RC circuit decreases with time.
