Question

16. The voltage needed to produce a current of 2 {~A} \) in a resistance of 15 \Omega \) is ( 2 points) (a) 30 {~V} \) (b) 7.5 {~V} \) (c) 8.8 {~V} \) (d)

Answer 1

To calculate the voltage needed to produce a current of 2 A in a resistance of 15 Ω, we can use Ohm's law, which states that the voltage (V) is equal to the product of the current (I) and the resistance (R):

V = I * R

Substituting the given values, we get:

V = 2 A * 15 Ω = 30 V

So the correct answer is (a) 30 V.
