Can yall me?
a. what is the effect on the current through a circuit of steady resistance when the voltage is increased by a factor of 2? find the ratio of the current after the change of voltage ifinal1 and the current before the change of voltage iinitial1.
b. what is the effect on the current if both voltage and resistance are increased by a factor of 2? find the ratio of the current after the change of voltage and resistance ifinal2 and the current before the change of voltage and resistance iinitial2.

Explanation:

Ohm's law describes the relationship between voltage, current, and resistance.

V = IR

where V is voltage, I is current, and R is resistance.

A. At the original voltage:

V₁ = I₁ R₁

When the voltage is doubled and resistance stays the same:

2V₁ = I₁' R₁

Dividing the two equations:

2V₁ / V₁ = (I₁' / I₁) (R₁ / R₁)

2 = I₁' / I₁

So the new current is double the original current.

B. At the original voltage and resistance:

V₂ = I₂ R₂

When both the voltage and resistance are increased by a factor of 2:

2V₂ = I₂' (2R₂)

Dividing the two equations:

(2V₂ / V₂) = (I₂' / I₂) (2R₂ / R₂)

2 = (I₂' / I₂) (2)

1 = I₂' / I₂

So the new current is the same as the original current.
