Given information
Consider the network of resistors , , and with a switch .
The current through each resistor when the switch is closed is :
Step-by-step explanation
Step 1.
Consider the network of resistors , , and with total current is shown in the figure :
By Ohm's law, we have
Since the resistance is constant to each of these and the current is going to change exactly how the voltage changes.
That means
Since is in series with the battery current will increase then its voltage will increase. That means current to will also increase
Since initially has no current the voltage across will increase when the switch is closed. That means current to will also increase
