question 219

Multiple Choice

Solve.
-The maximum number of volts, E, that can be placed across a resistor is given by the formula $\mathrm { E } = \sqrt { \mathrm { PR } }$ , where $\mathrm { P }$ is the number of watts of power that the resistor can absorb and $R$ is the resistance of the resistor in ohms. If a $\frac { 1 } { 4 }$ -watt resistor has a resistance of 10,000 ohms, find the largest number of volts of electricity that could be placed across the resistor.

• A) 50 volts
• B) 25 volts
• C) 100 volts
• D) 2500 volts
