The total effective resistance of several resistors in SERIES is just the sum of all the individual resistances.
So the effective resistance of ten 120-ohm resistors in series is
(120 + 120 + 120 + 120 + 120 + 120 + 120 + 120 + 120 + 120) .
A much easier way to write it is . . . (10) x (120) .
Total effective resistance = <em>1,200 ohms</em> .
Answer:
The process of crystal forming is called crystallization. Crystals often form in nature when liquids cool and start to harden. Certain molecules in the liquid gather together as they attempt to become stable. In nature, crystals can form when liquid rock, called magma, cools.

The power delivered to the coil is 0.5 Watts
<h3>Resistivity of a material</h3>
The formula for calculating the power delivered to it is expressed according to the equation
Power = I²R
where
I is the current
R is the resistance
Given
Current = 0.500A
Determine the resistance using the resistivity formula
R = ρL/A
Substitute the given parameters
R = 10^-6*(25)/0.002²
R = 2ohms
Substitute
Power = I²R
Power = (0.5)²(2)
Power = 0.5watts
Hence the power delivered to the coil is 0.5 Watts
