A current of 200mA through a conductor converts 40 joules of electrical energy into heat in 30 seconds determine the potential d
1 answer:
Answer:
V = 6.65 [volt]
Explanation:
We must first find the power generated, power is defined as the amount of energy consumed or generated in a given time.
where:
P = power [w]
E = energy = 40 [J]
t = time = 30 [s]
Now we can calculate the voltage or potential drop by means of the power, the power is calculated by means of the product of the voltage by the current.
where:
V = voltage [volts]
I = current = 200mA = 0.2 [A]

The elctromagnetic spectrum ranges from the radiowaves to the gamma rays. The whole spectrum is shown in the attached picture. But the optical telescope can only see the visible region. So, it only covers from the 400 nm to 700 nm frequency. It follows the ROYGBIV colors, where red has the highest frequency and violet has the lowest frequency.
