Question

A flashlight is connected to a dry cell of voltage 3.50 V. It draws 20.0 ma (1000 ma = 1A) what is the resistance?

175 ohm

225 ohm

350 ohm

400 ohm
​

Answer 1

a. 175

Step-by-step explanation:

equation= R=V/I

R= resistance

V= voltage

I= current

so just substitute, R= 3.50/20.0

which is 0.175

all u need to do is 0.175 x 1000

which is 175

(the other person got it right i just wanted to show how it was done incase anyone wanted)

Answer 2

175 ohm

Step-by-step explanation:

i worked it on on a seprate sheet so its hard to explain
