In series circuit, Req = R₁ + R₂ + R₃ + ···
In parallel circuit,
total resistance in the upper branch = R₂ + R₃ = R₂ + 2
R₂ + 2 = 12
R₂ = 10Ω
<h3>Q8.</h3>Req = 1.7Ω
Answer:
The induced emf between two end is V
Explanation:
Given:
Length of rod m
Height m
Magnetic field T
For finding induced emf,
Where velocity of rod,
For finding the velocity of rod.
From kinematics equation,
Where initial velocity,
Put the velocity in above equation,
V
Therefore, the induced emf between two end is V
