-For a Resistor in a Direct Current Circuit That $\frac { 1 } { 16 }$

question 115

Multiple Choice

Solve.
-For a resistor in a direct current circuit that does not vary its resistance, the power that a resistor must dissipate is directly proportional to the square of the voltage across the resistor. The resistor must dissipate $\frac { 1 } { 16 }$ watt of power when the voltage across the resistor is 14 volts. Find the power that the resistor must dissipate when the voltage across it is 28 volts.

• A) \(\frac { 7 } { 8 } \mathrm { watt }\)
• B) \(\frac { 49 } { 4 }\) watts
• C) \(\frac { 1 } { 4 } \mathrm { watt }\)
• D) \(\frac { 1 } { 8 } \mathrm { watt }\)
