Answer :
The current in the 8 resistor has been decaying to half its initial amount for 0.693 Ms, or since the switch was closed. The movement of electrical charge carriers like electrons is known as current.
A resistor is an electrical component with two terminals that implements electrical resistance as a circuit element. Resistors are employed in electronic circuits for a variety of purposes, including lowering current flow, adjusting signal levels, dividing voltages, biassing active devices, and terminating transmission lines.
According to Ohm's rule, the resistance serves as the constant of proportionality, with the voltage (V) across a resistor being proportional to the current (I) (R).
