Answer 1

Heya!
--------


➖1. Equivalent Resistance -
==========================


◾The two Four Ohm Resistors are connected in PARALLEL


◾In Parallel Combination , Effective Resistance is Given By - >



$= > \frac{1}{rp} = \frac{1}{r1} + \frac{1}{r2}$


◾Hence Effective Resistance for Parallel Combination =>


$= > \frac{1}{rp} = \frac{1}{4} + \frac{1}{4} \\ \\ = > \frac{1}{rp} = \frac{2}{4} \\ \\ = > resistance \: = \frac{4}{2} = 2 \: ohm................ |1|$



◾The 1 Ohm Resistor is Connected in Series With the two 4 Ohm Resistors.


=> In Series Combination, Effective Resistance is Given By :


↪Rs = R1 + R2 + R3..........



Hence , the total Effective Resistance in the Entire Combination is :


✔ 2 + 1 = 3 Ohm




➖Total Current in the Circuit
==========================


↪Using Ohm's Law


◾Potential Difference ( V ) = Current ( I ) × Resistance ( R )


=> Here ,


▪Potential Difference = 12 V

▪Resistance = 3 Ohm

▪Current = ?



=> We have ,


=> 12 = 3 × I

=> I = 12/3



✔Current = 4 Ampere .
