The formula V=IR shows the relationship between voltage, current, and resistance. Solve this formula for R

netineya [11]

Answer:

The formula is $R =\frac {V}{I}$

Step-by-step explanation:

The formula V = I R shows the relationship between voltage, current, and resistance.

It is given by the Ohm's law.

According to this law, at constant temperature, the current flows in any conductor is directly proportional to the potential difference applied.

V = I R

where, V is the potential difference, I is the current and R is the resistance.

The resistance is given by

$R = \frac{V}{I}$

There is 3/8 of an apple pie left from dinner. Tomorrow, Victor plans to eat 5/8 of the pie that was left. Enter how much of the

Tcecarenko [31]

Answer:

$\frac{15}{64}$ of the pie

Step-by-step explanation:

Whole numbers refer to a collection of natural numbers together with 0.

Fraction refers to part of a whole.

Part of an apple pie left from a dinner = $\frac{3}{8}$

Part of an apple eaten by Victor tomorrow is equal to $\frac{5}{8}$ of the pie that was left

So,

Part of an apple eaten by Victor tomorrow = $\frac{5}{8}(\frac{3}{8})=\frac{15}{64}$ of the pie
