the maximum number of volts,E, that can be placed across a resistor is given by the formula E=sq root 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 Eif P=1/8 watts and R= 12800 ohms A20 volts B. 40 volts C. 1600 volts D. 80 volts

OpenStudy (campbell_st):

just substitute your given values \[E = \sqrt{\frac{1}{8} \times 2800}\] and evaluate

OpenStudy (anonymous):

E = sqrt(PR) which is\[E = \sqrt{PR}\]Just multiply P by R first, then take square root.

"1" in front of the "2800"

i have tried everythign nothign is coming close to the answer

OpenStudy (campbell_st):

sorry for the typo try \[E = \sqrt{\frac{1}{8} \times 12800}\]
