In reading the instruction manual that came with your garagedoor opener, you see that the transmitter unit in your car produces

iVinArrow [24]

Answer:

0.09221 V/m

Explanation:

$\mu_0$ = Vacuum permeability = $4\pi \times 10^{-7}\ H/m$

P = Power of transmitter = 250 mW

r = Distance to source = 42 m

c = Speed of light = $3\times 10^8\ m/s$

$E_0$ = Electric field amplitude

Intensity of a wave is given by

$I=\frac{P}{4\pi r^2}\\\Rightarrow I=\frac{250\times 10^{-3}}{4\pi \times 42^2}\\\Rightarrow I=1.12779\times 10^{-5}\ W/m^2$

Intensity is also given by

$I=\frac{E_0^2}{2\mu_0 c}\\\Rightarrow E_0=\sqrt{I2\mu_0 c}\\\Rightarrow E_0=\sqrt{1.12779\times 10^{-5}\times 2\times 4\pi \times 10^{-7}\times 3\times 10^8}\\\Rightarrow E_0=0.09221\ V/m$

The electric field amplitude at the receiver when it first fails is 0.09221 V/m

A circuit has a voltage drop of 60.0 V across a 120.0 resistor that carries a current of 0.500 A. What is the power conducted by

olasank [31]

Answer:

Power, P = 30 W

Explanation:

We have,

Voltage drop of a circuit is 60 V

Resistance of the resistor is 120 ohms

Current across the circuit is 0.5 A

It is required to find the power conducted by the resistor. Power conducted by a resistor is given by :

$P=VI$

V and I are voltage and current

$P=60\times 0.5\\\\P=30\ W$

So, the power conducted by the resistor is 30 watts.
