Answer:

Explanation:1ampere

Answer 2

Explanation:

Given Find the current in 1 ohm resistor  

• Using Kirchoff’s law we get
• So – 6 + 3I1 + 1 (I1 – I2) = 0
• So 3I1 + I1 – I2 = 6
• Or 4 I1 – I2 = 6---------1
• So – 9 + 2 I 2 + 1(I 2 – I 1) + 3 I 2 = 0
• So – 9 + 2 I2 + I 2 – I 1 + 3 I 2 = 0
• Or – I1 + 6 I 2 = 9 ---------------2
• Solving 1 and 2 we get
• 4 I 1 – I 2 = 6
• -I 1 + 6 I2 = 9 multiply by – 4
• So 4 I 1 – I 2 = 6
•     4 I 1 – 24 I2 = - 36
•              23 I 2 = 42
• So I 2 = 42 / 23 Amperes
• Also I 1 = 45 / 23 A
• Now net current across 1 ohm resistance will be I 1 – I 2  
•                                                                        = 45 / 23 – 42 / 23  
•                                                                        = 3 / 23 A from Q to P
•                                                                       = 0.13 A from Q to P
