Answer:

Explanation:

Wave be is way less softer but wave a is softer you can see by the way it moves. You can also think about it as real waves from a beach, you can tell that wave a is softer.

Think about the electricity sent to your home from a power plant. How does the voltage of the electricity that leaves the plant

creativ13 [48]

Answer:

C) High voltage to low voltage

Explanation:

At a power plant, there is a production of electricity at a high voltage compared to the voltage provided to our home.

Voltage of about 12 KV is produced by power plant which is then converted into about 400 KV or greater (depending upon the countries) to transfer electricity from power plant to city Grid station using Step-up transformer. At City Grid station, Step-down transformer is used to convert high voltage (about 400 KV) to low voltage (about 13 KV) to transfer electricity from grid station to the city. Then this low voltage (about 13 KV) again converted to 220 V using Step-down transformer for household usage. So, overall about 12 KV voltage at power plant is converted into 220 V for household usage using step-up and step-down transformer at different stages.

You connect five identical resistors in series to a battery whose EMF is 12.0 V and whose internal resistance is negligible. You

avanturin [10]

Answer:

The resistance of each resistor is 2.5 Ω

The potential difference across each resistor is 2.4 V.

Explanation:

By Ohm's law,

V = IR

where V is the potential difference or voltage across an element, I is the current flowing through it and R is its effective resistance.

For the group of five resistors, let their combined resistance be R.

Then

(12.0 V) = (0.961 A)(R)

$R = \dfrac{12}{0.961}\,\Omega$

Because they are in series, R is the arithmetic sum of their individual resistances. Because they are all identical, the resistance of each resistor is

$= \dfrac{12}{5\times0.961}\,\Omega = 2.5\,\Omega$

Also, because they are in series and are equal, the EMF is distributed across them equally. Therefore, the potential difference across each resistor is

$\dfrac{12.0\text{ V}}{5} = 2.40\text{ V}$
