Find the current in 2 ohms resistor, refer to the following attachment |
|
Answer» he circuit on the LEFT side,Potential difference = 10 VResistance = 5 ΩWe KNOW,V = IR⇒10 = I × 5⇒I = 10/5⇒I = 2 A◙ For the circuit on the right side,Potential difference = 20 VResistance = 10 ΩWe know,V = IR⇒20 = I × 10⇒I = 20/10⇒I = 2 AAs the 2 Ω resistor is connected with both the circuits in series, so the current flowing through the 2 Ω resistor is 2 - 2 = 0 A. (As the current of 2 A is reserved for the RESPECTIVE circuits, and don't flow beyond that.) |
