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.

Increasing the amplitude of a traveling wave with a period T will

goblinko [34]

<span>Amplitude is the maximum extent of vibration
As by increasing the amplitude the wave speed ,frequency and wavelength will remain same so it will increase </span><span>the speed of the individual particle in the medium.
This will increase wave energy
so correct option is B
