You have a large flashlight that takes 4 D-cell batteries, each with a voltage of 1.5 volts. If the current in the flashlight is 2.0 amps, what is the resistance?

Respuesta :

resistance = voltage/current
= 1.5v/2amp
= .75 ohm

Answer:

3 ohm

Explanation:

Use the concept of Ohm's law

V = I × R

Voltage of each battery = 1.5 V

Voltage of 4 batteries = 4 × 1.5 = 6 V

Current I = 2 A

6 = 2 × R

R = 3 ohm
