An LR Circuit Is Hooked Up to a Battery as Shown

question 73

Multiple Choice

An LR circuit is hooked up to a battery as shown in the figure,with the switch initially open.The resistance in the circuit is R = 11.0,the inductance is L = 3.00 H,and the battery maintains a voltage of E = 36.0 V.At time t = 0 the switch is closed.How much time (in seconds) does it take until the voltage across the resistor is equal to the voltage across the inductor?

• A)0.189
• B)0.236
• C)0.295
• D)0.369
• E)0.462

Definitions:

Higher Altitudes

Regions located at a great height above sea level, often associated with lower atmospheric pressure and decreased oxygen levels.

Partial Pressure

The pressure that a single component of a mixture of gases would exert if it alone occupied the entire volume of the mixture at the same temperature.

Atmospheric Gases

The gases that make up Earth's atmosphere, including nitrogen, oxygen, carbon dioxide, and argon, among others.

Oxygen Saturation

A measure of the amount of oxygen carried by hemoglobin in the blood, usually expressed as a percentage of the maximum carrying capacity.
