Question

Find the resistance if the current is 1.5 amperes and the voltage is 15-V.

Answer 1

The resistance = B. 10 Ω

Further explanation

Electric current (symbolized by the letter "i) is the amount of charge flowing in the conductor of each unit of time  

The international standard unit of electric current is Coulomb/second or Ampere (A).  

Electric current is also a ratio between the voltage and the amount of resistance at the conductor.  

Can be formulated  

$\large{\boxed{\bold{I=\frac{V}{R}}}$

V = Voltage (volts)  

R = resistance (ohms)  

This formula is also known as Ohm's Law, which states that  

the amount of current flowing is directly proportional to the voltage and inversely proportional to the resistance.  

The current is 1.5 amperes and the voltage is 15-V, so :

$\tt I=1.5~A\\\\V=15~V$

The resistance :

$\tt R=\dfrac{V}{I}\\\\R=\dfrac{15}{1.5}\\\\R=\boxed{\bold{10~ohm}}$
