Question

2 A sensor uses 5*10-3A of current when it is operated by a 5.0-V battery. What is the resistance of the sensor circuit?

Answer 1

`10^(3)Ω` or 1000 Ohms

Step-by-step explanation:-

The relationship between current, voltage and resistance is given by Ohms Law.

`V=IR`

where

V = Voltage

I = Current

R = Resistance

Now in our case, we are told that,

V = 5.0 V

I = 5×
`10^( - 3)`amperes

Therefore, the above equation gives

`5.0 = (5 * {10}^( - 3))R`

Dividing both sides by 5×
`10^( - 3)` gives,

R = 5.0 ÷ 5×
`10^( - 3)`

=> R =
`10^(3)Ω`

Hence, the resistance of the sensor circuit is
`10^(3)Ω` or 1000 Ohms
