Question

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

Answer 1

option b

Step-by-step explanation:

according to Ohms law

Voltage, V = Current I × Resistance, R

`V = IR\\\\where\\\\R = (V)/(I)`

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

`R \alpha (1)/(I)`

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

also

As R decreases I increases
