A 100 V battery is connected across a

Sergio039 [100]

1 mA = 0.001 A

Therefore, 5 mA = 0.001 * 5

=0.005 A

Resistance = voltage / current

= 100 / 0.005

= 20000 ohms

Current = voltage / resistance

= 25 / 20000

= 0.00125 A (or) 1.25 mA

Answer:

$\frac{dB}{dt} = 11.55 T/s$

Explanation:

As we know that flux of magnetic field from the closed loop is given by

$\phi = BAcos30[tex]now by Faraday's law we know[tex]EMF = \frac{d\phi}{dt}$

now we will have

$EMF = Acos30\frac{dB}{dt}$

now we have

$A = 1 m^2$

EMF = 10 Volts

$10 = 1 (cos30)\frac{dB}{dt}$

$\frac{dB}{dt} = \frac{20}{\sqrt3}$

$\frac{dB}{dt} = 11.55 T/s$
