Question 675361: The maximum number of volts, E, that can be placed across a resistor is
given by the formula E = PR, where P is the number of watts of power
that the resistor can absorb and R is the resistance of the resistor in ohms.
Find E if P = 12
watts and R = 72 ohms.

The maximum number of volts, E, that can be placed across a resistor is
given by the formula E = PR, where P is the number of watts of power
that the resistor can absorb and R is the resistance of the resistor in ohms.
Find E if P = 12
watts and R = 72 ohms.
---------------
Using E = P*R --> 12*72 = 864 volts
=======================================
But that formula is not correct.
Actually P = E^2/R
-->
E =~ 29.4 volts
-------------------
Also, resistors don't absorb power, they dissipate it as heat.
