Question

please answer this physics question. ​

Answer 1

Answer:a}20/7 b}yes

Explanation: Total Resistance =6ohm+8ohm=14 ohm

V=IR

5=I×14

I=5/14

Potential difference across8ohm resistor

V=IR

V=5/14×8

V=20/7

b}beacuse as the total resistance will current capacity of 8ohm resistor will be greater than other one

Answer 2

Explanation:

a]

Net resistance in the circuit = 8Ω + 6Ω = 14Ω

Total current in the circuit = V/R = 5/14 A

Potential difference across "8Ω" = iR

= 5/14 × 8

= 20/7 volts

b] smaller

Reason: Net resistance of circuit is decreased if another resistor is connected to 6Ω resistor in parallel.

Net current therefore is increased (since i prp 1/R when V is constant)

Hence, potential difference now at 8Ω resistor is 8 × (number less than 5/14) = <20/7 volts
