Question

The current through a 13 kilo-ohms [k Ohm] resistor is 24 microamps [mu A]. What is the voltage across the resistor? Click the icon to view the table that summarizes the electrical properties. The voltage across the resistor is V. (Round your answer to three significant digits.) A 800-ohm [O] resistor has 140 volts [V] across it. What is the minimum wattage rating of the resistor? Click the icon to view the table that summarizes the electrical properties. The minimum wattage rating of the resistor is V. (Round your answer to three significant digits.) The temperature of dry ice is - 109.3 degrees Fahrenheit [degree F]. Convert this temperature into units of kelvin [K]. Click the icon to view conversion formulas for temperature scales. Click the icon to view the factors for conversions involving temperature differences. The temperature is K. (Round your answer to three significant digits.)

Explanation / Answer

a)

V = i R = (24e-6) * (13e3) = 0.312 Volt

------------------

b)

P = V^2/R = (140*140)/(800) = 24.5 W

------------------

c)

195 K
