Ohm’s Law states that the electrical current, I in amperes, through a resistor is given by the formula 1=v/r where V is the voltage in volts and R is the resistance in ohms. If the current is 6 amperes and the resistance is 18 ohms, what is the voltage?
 a. 
 3 volts 
 c. 
 87 volts 
 b. 
 215 volts 
 d. 
 108 volts
