To measure the current through the solenoid, a 5.00 resistor was placed in serie

Question

To measure the current through the solenoid, a 5.00 resistor was placed in series with the solenoid, the voltage across the resistor was measured, then the current was computed using Ohm's law. Which of the following would happen if that resistor was replaced a larger 500 resistor while keeping everything else the same?

Select all that apply!

___ the current through the solenoid would increase

___ the current through the solenoid would decrease

___ the current through the resistor would increase

___ the current through the resistor would decrease

___ the solenoid's magnetic field strength would increase

___ the solenoid's magnetic field strength would decrease

Explanation / Answer

Here ,

Resistance , R = 5 Ohm

when a new resistance R = 500 Ohm is applied

Using Ohm's law

I = V/R

as R is increased

the current in the solenoid will decrease.

magnetic field strength = u0 * N * I

the solenoid's magnetic field strength would decrease

the options are :

the solenoid's magnetic field strength would decrease

the current through the solenoid would decrease

the current through the resistor would decrease
