Answer:
The current in the resistor is 1.1304 mA.
Step-by-step explanation:
Given that,
Radius = 4.00 cm
Number of turns = 500
Magnetic field

Resistance

Time t = 5.00 s
We need to calculate the emf
Using formula of emf

Where, A = area
N = number of turns
B = magnetic field
Put the value into the formula


We need to calculate the current in the resistor at t = 5.00
Using formula of current


Where, R = resistance
Put the value into the formula

Put the value of t in equation (II)




Hence, The current in the resistor is 1.1304 mA.
