Write the help of given diagram calculate the current through each resistor..

= 3 A

= 1.8 A

= 1.2 A

Explanation:

Combined resistance of the resisters B and C,

[Since and are attached in parallel]

R' = 2.4 Ω

Since, R' and resistor A are in series therefore, total resistance of both the resistors = 2 + 2.4

= 4.4 Ω

Now the current flowing in the circuit 'i' =

Here, E = E.M.F. of the cell

R = Total resistance of all resistors attached

r = Resistance of the cell

'i' =

i = 3 A

Current flowing in resistor A = 2 A

And Current in combined resistance of B and C = 3 A

Current flow in the resistors B and C will be in the ratio of C : B,

Therefore, = = 1.2 A

= 1.8 A

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
