Given information
All have the same resistance
Voltage
The current through each resistor before
and after closing the switch
Qualitative predictions confirmed =?
Step-by-step explanation
Step 1.
Consider the network of resistors , , and with total current is shown in the figure :
Case 1:
When the switch is open:
and are in parallel combined with in series.
The equivalent resistance is given by :
Current from the battery is given by :
Since there are increases in current and
because in series connection with the battery
