Question

what is the voltage of an electric car that has 17 ohms of resistance and draws a current of 27 amps?
44 volts
0.63 volts
459 volts
1.59 volts

Explanation:

Step1: Recall Ohm's Law

Ohm's Law is $V = I \times R$, where $V$=voltage, $I$=current, $R$=resistance.

Step2: Plug in values

$I=27$ amps, $R=17$ ohms. Calculate $V=27 \times 17$.

Step3: Compute the product

$27 \times 17 = 459$.

Answer:

C. 459 volts
