A series circuit contains three 2 Ω resistors and a 6 Ω resistor. The current in each resistor is 4. 0 A. What is the voltage of
Delvig [45]

The voltage is a representation of the electric potential energy per unit charge.

The voltage across the circuit is 48 V. Option D shows the voltage across the circuit.

<h3>What is the voltage?</h3>

Voltage is defined as the difference in electric potential between two points.

Given that a series circuit contains three 2 Ω resistors and a 6 Ω resistor. The current in each resistor is 4.0 A.

The total resistance across the series circuit is given below.

R = R_1 + R_2 + R_3 + R_4

Where R is total resistance, R1, R2, R3 and R4 are resistors that are connected in series.

R = 2+ 2+2+6

R = 12 \;\rm ohm

The resistors are connected in series hence the current flows across the two points of the circuit are the same which is 4.0 A.

The voltage across the circuit is,

V = IR

V = 4.0 \times 12

V = 48.0 \;\rm V

Hence we can conclude that the voltage across the circuit is 48 V. Option D shows the voltage across the circuit.

To know more about the voltage, follow the link given below.

Simplify the trigonometric expression tan(2x)/tan(x) using double-angle identities !!
jok3333 [9.3K]

 

\displaystyle\\\text{We use the formula: }~~~\tan(2x)=\frac{2\tan(x)}{1-\tan^2(x)}\\ ---\\\\\frac{\tan(2x)}{\tan(x)}=\frac{\dfrac{2\tan(x)}{1-\tan^2(x)}}{\tan(x)}=\frac{2\tan(x)}{\tan(x)\Big(1-\tan^2(x)\Big)}=\boxed{\frac{2}{1-\tan^2(x)}}\\\\\\ \text{Correct answer:~~A.}

Which monomials are perfect squares? Select three options.
aliya0001 [1]

Answer:

a, d and e.

Step-by-step explanation:

A perfect square is one where the coefficient is a perfect square and the exponent is even.

So they are 25x^12, 36x^16 and 9x^8.
