<span>When two or more identical capacitors (or resistors) are connected
in series across a potential difference, the potential difference divides
equally among them.

For example, if you have nine identical capacitors (or resistors) all
connected end-to-end like elephants in a circus parade, and you
connect the string to a source of 117 volts (either AC or DC), then
you will measure

(117v / 9)  =  13 volts

across each unit in the string.</span>

You have a circuit with a 50 Ω , a 100 Ω , and a 150 Ω - resistor connected in series. (a) Rank the current through them from hi
olga2289 [7]

Explanation:

(a) A circuit has 50 Ω, a 100Ω and a 150 Ω resistor are connected in series. We know that in series combination, current through each resistor is same. So, current through a 50 Ω, a 100Ω and a 150 Ω resistor is same.

(b) Ohm's law of given by :

V = I R

V is potential difference. As I is same, so, the resistor having highest resistance will have highest potential difference. So,

V_3>V_2>V_1.

Hence, this is the required solution.

Displacement vectors of 10 m west and 14 m west make a resultant vector that is ?
goldenfox [79]

Resultant vector= 24 m west.

Explanation:

resultant vector= r1+ r2 when the two vectors are in same direction

r1=10m west

r2= 14 m west

so resultant displacement= 10 + 14

resultant displacement= 24 m west

A sphere with a charge q is fixed at the bottom left corner of the right triangle shown in the figure. Points P and R are at the
Alexus [3.1K]

Answer:

the final potential energy of this system is 3U0/10

Explanation:

We are given

charge at left end  and another test charge at point p

Potential energy is given by  = \frac{k*Q1*Q2 }{R}

where k is electrostatics constant = 9 *10^9

Q1 = first charge , Q2=  test charge

R= distance between charges

potential at point p

U0 = k*Q1*Q2 /3 ⇒ kq1q2 = 3U0 ..............1

now the test charge moves to point R

using Pytahgoreou theorem

R(distance) = \sqrt{8^2 + 6^2} = 10

New Potential energy

U1 = kq1*q2 / 10

substituting  kq1q2 = 3U0 from 1

U1 = 3U0/10

So this is the final potential energy of this system.
