Answer 1

R = 150

| = 0.8 Ampere

Step-by-step explanation:

From the given figure, we can say that ; R1 and R2 are in the series, for series we add resistance simply as shown below,

R1 + R2 = ( 10 + 20 ) 0

- R1 + R2 = 30 22

And, Resistance R3 and R4 are in the series, therefore

R3+ R4 = ( 5 + 25 ) 12

» R3 + R4 = 30 22

Now, R1 + R2 and R3 + R4 are parallel resistors,

1/30 + 1/30

- 1+1/30

- 2/30

→ 1/15

Hence, total resistance = 152

We know that,

V = IR

[ where, V = volt, I = current, R = resistance]

- 12 = 1 * 15

+ 1 = 12 / 15

- 1 = 0.8 Ampere

Hence, total resistance is 15 2 and total current flowing is 0.8 Ampere
