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?

Sagot :

[tex]10^{3}Ω[/tex] or 1000 Ohms

Explanation:-

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

[tex]V=IR[/tex]

where

V = Voltage

I = Current

R = Resistance

Now in our case, we are told that,

V = 5.0 V

I = 5×[tex]10^{ - 3}[/tex]amperes

Therefore, the above equation gives

[tex]5.0 = (5 \times {10}^{ - 3})R[/tex]

Dividing both sides by 5×[tex]10^{ - 3}[/tex] gives,

R = 5.0 ÷ 5×[tex]10^{ - 3}[/tex]

=> R = [tex]10^{3}Ω[/tex]

Hence, the resistance of the sensor circuit is [tex]10^{3}Ω[/tex] or 1000 Ohms
