A current of 0. 82A flows through a light bulb. The charge passed through the light bulb during 94 s is 77.08C
The amount of charge flown for a given period of time determines the current passed through a bulb or electrical body.
The relation between the charge, current and time is given as:
Q = I × t
where, Q is the charge flown through bulb
I is the current passed through bulb
t is the time for which charge passes through bulb
Given,
I = 0.82A 
t = 94s
Q = ?
Substituting the values in the above formula:
Q = I × t
Q = 0.82 × 94
Q = 77.08C
Hence, The charge passed through the light bulb during 94 s is 77.08C

Answer:

Explanation:
Given,
Magnetic field, B = 5 x 10⁻⁵ T 
Number of turns, N = 450 
length = 29 cm
Current,I = ?
Using formula of magnetic field due to solenoid
 



Hence, the current obtained is equal to 0.0256 A.
