Question

Calculate the current flowing through each of the resistors A and B ​

Answer 1

Answer:

Total I of circuit = V/Req

Req = 2*1/2+1

= 2/3 ohm

thus, total I = 2*3/2= 3 A

current through A = 2/1= 2A

current through B = 2/2= 1 A

we can check the ans as sum of both the values shud be equal to 3A

Answer 2

$\huge{\pink{\underline{\underline{Answer:-}}}}$

Given:

Resistor are in parallel

R1 = 1 ohm

R2 = 2 ohm

V = 2 volt

To find:

Current in resistor 1 and 2

Solution:

In parallel, voltage is same in every branch and current is different in every branch

we know, V= IR

Let,

Consider resistor A as R1 and resistor B as R2

current in resistor R1 is I1 and current in resistor R2 is I2

1) V = I1 × R1

2 = I1 × 1

I1 = 2/1

I1 = 2 A

2) V = I2 × R2

2 = I2 × 2

I2 = 1 A

Required answer:

Therefore, current in resistor A is 2 Ampere and current in resistor B is 1 ampere

Basic points:

# In series current is same and voltage is different

# Unit of current is ampere, of voltage is volt and resistance is ohm
