question 67

Multiple Choice

In electronics, the formula $V = I R$ is called Ohm's law. It gives the relationship in a circuit between the voltage $V$ (in volts) , the current $I$ (in amperes) , and the resistance $R$ (in ohms) .
Find $\mathrm { V }$ when $I = 8 - 3 i$ amperes and $R = 6 + 8 i$ ohms.

• A) \(\quad V = 82\) volts
• B) \(\quad V = 72\) volts
• C) \(\quad V = i\) volts
• D) \(\quad V = 72 + 82 i\) volts
• E) \(\quad V = 72 + 46 i\) volts
