What is the effect on the current in a simple circuit if both the voltage and the resistance are reduced by half?
a) Divided by 2
b) no change
c) Multiplied by 2
d) multiplied by 4

Respuesta :

Answer:

B-No change

Explanation:

Using Ohm's Law, V=IR, you can solve for the current and get V/R=I

Plugging in 1/2V and 1/2 R into the equation you will get [tex]\frac{0.5V}{0.5R}[/tex]=I. As a result, the 1/2s cancel out, leaving no change on the current.

This question involves the concepts of Ohm's Law and current.

The effet on the current in simple circuit if both voltage and resistance are reduced by half is "no change".

OHM'S LAW

According to Ohm's Law:

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

where,

  • I = current
  • V = voltage
  • R = resistance

After reducing voltage and resistance, current will become:

[tex]I'=\frac{\frac{V}{2}}{\frac{R}{2}}\\\\I' = \frac{V}{R}[/tex]

I' = I

Hence, there is no change in current.
