Explanation Consider the resistance of the resistor be R and voltage across the circuit be V . For circuit A : The switch is closed after a long time for circuit A and the inductor will act as short circuit. So, in circuit A equivalent resistance will be equal to the resistance. The equivalent resistance of the circuit A is, R e = R Here, R e is the equivalent resistance of the circuit. The current in the circuit A is, I A = V R Here, V is the electric potential of the circuit. I is the current through the circuit. Thus, the current in circuit A is V R . For circuit B : The switch is closed after the long time and the inductor will act as short circuit. One resistance in parallel with inductor is shorted. So, in circuit B equivalent resistance will be equal to the resistance Thus, the equivalent resistance of the circuit B is, R e = R The current in the circuit B is, I B = V R Thus, the current in circuit B is V R . For circuit C : The switch is closed after the long time of the circuit C and the inductor will act as short circuit. In this case two resistances of circuit C in parallel with inductor will be shorted. So, in circuit B equivalent resistance will be equal to the resistance. Thus, the equivalent resistance of the circuit C is, R e = R The current in the circuit C is, I C = V R Thus, the current in circuit C is V R

The rectangular loop of wire shown in the figure (Figure 1) has a mass of 0.18 g per centimeter of length and is pivoted about side ab on a frictionless axis. The current in the wire is 8.5 A in the direction shown. Find the magnitude of the magnetic field parallel to the y-axis that will cause the loop to swing up until its plane makes an angle of 30.0 ∘ with the yz-plane. The answer is .028 T, I just need help understanding how to do it. Please show all steps.

A ray of light from an object you want to look at strikes a mirror so that the light ray makes a 32 degree angle relative to the normal line (a line perpendicular to the surface of the mirror at the point where the ray strikes the mirror). If you want to see the object in the mirror, what angle does your line of sight need to make relative to the normal line? Give your answer as the number of degrees.

Suppose you have a converging lens with a focal length of 65 cm. You hold this lens 120 cm away from a candle. How far behind the lens should you place a notecard if you want to form a clear image of the candle, on the card? Give your answer as the number of centimeters.
