Three resistors are connected in parallel. If placed in a circuit with a 12-volt power supply. Determine the equivalent resistan

Ivan

(a) The equivalent resistance of three parallel resistors is (R₁R₂R₃)/(R₁R₂ + R₁R₃ + R₂R₃).

(b) The total circuit current is 12/R.eq.

<h3>Equivalent resistance of three parallel resistors</h3>

The equivalent resistance of three parallel resistors is calculated as follows;

Let the first resistor = R₁
Let the second resistor = R₂
Let the third resistor = R₃

$\frac{1}{R_{eq}} = \frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_2}\\\\R_{eq} = \frac{R_1R_2R_3}{R_1R_2 + R_2R_3 + R_1R_3}$

<h3>Total Circuit Current </h3>

The total circuit current is calculated as follows;

V = IR

$I= \frac{V}{R_{eq}} = \frac{12 \ V}{R_{eq}}$

<h3>Voltage drop in each resistor</h3>

Voltage drop in resistor 1 = IR₁

Voltage drop in resistor 2 = IR₂

Voltage drop in resistor 3 = IR₃

Astronomers study the electromagnetic radiation emitted by distant stars and planets to determine things like: how far away they

NeTakaya

Answer:

This same Hawaii telescope, which would be 4 km across water level, can't provide an appropriate version of distanced planetary bodies. A further overview is provided below.

Explanation:

The surface area of that same earth's orbit seems to be approximately 480 km heavy. The atmosphere isn't translucent to the only certain wavelength range of the radioactivity. Not because all-stars, as well as gliders, emit specific wavelengths, but several of them generate ultraviolet as well as infrared.
Those same radiations have either been mediated primarily as well as passes through the atmosphere. Due to the Blockage, they can't even be interpreted with such a similar quality unless the telescope would be positioned throughout the portion of the atmosphere.

A car is traveling north at 17.7m/s After 12 s its velocity is 14.1m/s in the same direction. Find the magnitude and direction o

dem82 [27]

Answer:

Option B

0.3 m/s2 South

Explanation:

Acceleration, $a=\frac {v-u}{t}$ where v and u are final and initial velocities respectively, t is the time taken

Substituting 14.1 m/s for v, 17.7 m/s for u and 12 s for t then

$a=\frac {14.1 m/s- 17.7 m/s}{12}=-0.3 m/s^{2}$

Since this is negative acceleration, it's direction is opposite hence 0.3 m/s2 South
