If you increase the resistance of a circuit, what happens to the current?

a
the current is not effected by this
b
the current decreases
c
the current stays the same
d
the current increases

Respuesta :

yemmy

Answer:

option b

Explanation:

according to Ohms law

Voltage, V = Current I × Resistance, R

[tex]V = IR\\\\where\\\\R = \frac{V}{I}[/tex]

from the above ohms law relation and making R the subject

let assume that voltage V is constant.

we can conclude that

R is inversely proportional to current I

that is

[tex]R \alpha \frac{1}{I}[/tex]

this means that as resistance, R increases in a circuit, current, I decreases

also

As R decreases I increases
