The number of electrons passes through 20 ohms resistor in 10 minutes is 5.625e+21.
<h3>What is a resistor?</h3>
In an electronic circuit, a resistor is an electrical component that limits or regulates the flow of electrical current.
Given, the resistance is 20 ohms.
The potential difference is 30 volts
Time is 10 minute
By the formula of current
The charge flowing through the resistor is 1.5 C/s
1 electron charge is 1.6e+19
Now, the number of electrons passing through a 20 ohms resistor is
In 10 minutes
Thus, the number of electrons passes through 20 ohms resistor in 10 minutes is 5.625e+21.

Answer:
True
You don't need sugar for energy. Carbo hydrates and protiens gets converted into glucose for energy. Whereas if you eat sugar it will mess with your glucose level in blood. It is linked with diseases and health hazards such as type 2 diabetes, heart diseases,obesity,cognitive dysfunction in children, aging faster,etc.
Morever as you age your body can't handle too much spike in blood sugar leading to t2d(insulin resistivity /low production of insulin).
Also as sugar crosses brain barrier easily, it will cause several brain diseases eventually.
