At the moment contact is made with the battery, the voltage across the inductor is zero
At the instant the switch is closed, there is no current in the resistor (the inductor has prevented that), and therefore, there is no voltage across the resistor
<h3>What is Voltage ?</h3>
When charged electrons (current) are forced through a conducting loop by the pressure of an electrical circuit's power source, they can perform tasks like lighting a lamp. In a nutshell, voltage equals pressure and is expressed in volts (V).
- DC voltage and AC voltage are the two different types of voltage. In a battery, for example, the DC voltage (direct current voltage) is always of the same polarity (positive or negative). Positive and negative waves interchange within the AC voltage (alternating current voltage).

Hi!
The weight force is given by: F = mg (mass x gravity)
Then, we have:
29 = m * 9.8
29/9.8 = m
m = 2.95 kg
;)
I believe the correct answer is false. The behaviors that light exhibits are reflection, refraction, diffraction but not polarization, and dispersion. Light<span> behaves as a wave - it undergoes reflection, refraction, and diffraction just like any wave would. Hope this answers the question.</span>
I would say that this is the first law of thermodynamics.
