The total current supplied to the circuit as shown in figure by the 5 V battery is _____ A .

Step-by-step solution

As in this case, 5   Ω & 5   Ω are in parallel hence, their combined resistance value will be 2 . 5   Ω . Now, this 2 . 5   Ω with existing 2 . 5   Ω are in series and hence can be combined to write 5   Ω . In the final diagram, we can write equivalent resistance across the battery as 2 . 5   Ω . Hence, current through the battery is, i = 5   V 2 . 5   Ω = 2   A
