1.) In the circuit shown a current of 0.45 A will pass through which of the following resistors?

R2

R1

R3

R4

2.) Which of the following statements is true about the circuit shown?

I1>I2>I3

I1>I3>I2

I1=I2=I3

I2>I3>I1

this means that the temperature of both substances will be equal

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
