Answer:

Explanation:

Given

Power drawn by toaster P_1=1840\ W

Power drawn by Electric fan P_2=1460\ W

Power drawn by lamp P_3=50\ W

Voltage applied V=120\ V

If appliances are applied in parallel then Voltage applied is same

Power is given by P=\frac{V^2}{R}

Resistance of toaster R_1=\frac{120^2}{1840}=7.82\ \Omega

Resistance of electric Fan R_2=\frac{120^2}{1460}=9.86\ \Omega

Resistance of toaster R_3=\frac{120^2}{50}=288\ \Omega

Current is given by

I=\frac{V}{R}

I_1=\frac{120}{7.82}=15.34\ A

I_2=\frac{120}{9.86}=12.17\ A

I_3=\frac{120}{288}=0.416\ A

Answer:

Explanation:

power of toaster, P1 = 1840 W

Power of electric frying pan, P2 = 1460 W

Power of lamp, P3 = 50 W

As they all are connected in parallel, so the voltage is same for all.

Let the current in toaster is i1.

P1 = V x i1

1840 = 120 x i1

i1 = 15.33 A

Let the current in frying pan is i2.

P2 = V x i2

1460 = 120 x i1

i1 = 12.17 A

Let the current in lamp is i3.

P3 = V x i3

50 = 120 x i3

i3 = 0.42 A

How do you test hydrogen gas
Vanyuwa [196]

Explanation:

A splint is lit and held near the opening of the tube, then the stopper is removed to expose the splint to the gas. If the gas is flammable, the mixture ignites. This test is most commonly used to identify hydrogen, which extinguishes with a distinctive 'squeaky pop' sound.

Determine the magnitude of the force between two 42 m-long parallel wires separated by 0.03 m, both carrying 6.3 A in the same d
xz_007 [3.2K]

Answer:

The magnitude of the force between the two parallel wires is 0.0111 N.

Explanation:

Given;

length of the two parallel wires, L = 42 m

distance between the two wires, r = 0.03 m

current in both wires, I₁, I₂ = 6.3 A

Therefore, the magnitude of the repulsive force between the two parallel wires is given by;

F = \frac{\mu_0 I_1I_2l}{2\pi r}\\\\where;\\\mu_0 \ is \ permeability \ of \ free \ space = 4\pi *10^{-7} \ T.m/A \\\\F = \frac{(4\pi *10^{-7})(6.3)^2(42)}{2\pi (0.03)}\\\\F =   0.0111 \ N

Therefore, the magnitude of the force between the two parallel wires is 0.0111 N.
