Question

How does the current in a circuit change if the resistance is doubled? The current is halved. The current is doubled. The current is multiplied by four. The current stays the same.

Answer 1

A

Step-by-step explanation:

Answer 2

The current is halved

Step-by-step explanation:

The relationship between the current and the resistance is given by Ohm's Law, as follows:

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

where,

V = Voltage

I = Current

R = Resistance

Therefore, if we double the resistance:

`I' = (V)/(2R)\\\\I' = (1)/(2)I`

Hence the correct option is:

The current is halved
