Solution Summary
This solution provides a step-by-step explanation of how to calculate the given electrical physics questions.
Solution Preview
Please see the attachment for the complete solution response.
a) As the switch is closed at t = 0, full battery voltage comes across resistance R_1. Hence, potential difference across R_1 at t= 0 is 60 V.
b) The positive terminal of the battery is connected to point a and the negative terminal to b and as we know, +ve terminal of a battery is at a higher potential with respect to the -ve terminal. Hence, point a is at a higher potential than point b.
c) At t = 0, the current through the series combination of R_2 and ...
