The total resistance of a parallel circuit is 25 ohms. If the total current is 100mA, how much current is through a 220 ohm resi

gulaghasi [49]

Answer:

The current across the resistance is 0.011 A.

Explanation:

Total resistance, R = 25 ohms

Total current, I = 100 mA = 0.1 A

Let the voltage is V.

By the Ohm's law

V = I R

V = 0.1 x 25 = 2.5 V

Now the resistance is R' = 220 ohm

As they are in parallel so the voltage is same. Let the current is I'.

V = I' x R'

2.5 = I' x 220

I' = 0.011 A

To make ice, a freezer that is a reverse Carnot engine extracts 37 kJ as heat at -17°C during each cycle, with coefficient of pe

Dvinal [7]

Answer:

a) 6.4 kJ

b) 43.4 kJ

Explanation:

$Q_{a}$ = Heat absorbed = 37 kJ

$β$ = Coefficient of performance = 5.8

$W$ = Work done

Heat absorbed is given as

$Q_{a}$ = $β$ $W$

37 = (5.8) $W$

$W$ = 6.4 kJ

$Q$ = work per cycle required

$Q$ = $Q_{a}$ + $W$

$Q$ = 37 + 6.4

$Q$ = 43.4 kJ

Which of the following correctly identifies the initial direction of the force on the moving positively charged particle (i.e.,

meriva

Answer:

Explanation:

Given

Current is flowing towards right side

Considering right side i.e. +x to be positive and direction outside the paper be +k

suppose charge is below the wire and is moving towards right

$v=v_0\hat{i}$

magnetic field below the wire is outside the Paper using right hand thumb rule

$B=B_0\hat{k}$

$F=q(\vec{v}\times \vec{B})$

$F=q(v_0\hat{i}\times B_0\hat{k})$

$F=-qv_0B_0\hat{j}$

i.e. Force acts in Downward direction

i charge is moving towards left i.e.

$v=-v_0\hat{i}$

$F=q(-v_0\hat{i}\times B_0\hat{k})$

$F=qv_0B_0\hat{j}$ towards upward direction
