The equation for the speed of an electromagnetic wave is
igomit [66]

Answer:

c = 1 / √(ε₀*μ₀)

Explanation:

The speed of the electromagnetic wave in free space is given in terms of the permeability and the permittivity of free space by

c = 1 / √(ε₀*μ₀)

where the permeability of free space (μ₀) is a physical constant used often in electromagnetism and ε₀ is the permittivity of free space (a physical constant).

A circuit has an impedance of 5 ohms and a voltage of 100 volts. What is the current flow?
Ket [755]

A circuit with an impedance of 5 ohms and a voltage of 100 volts has a current flow of 20 A.

The expression of an electronic component, circuit, or system's resistance to alternating and/or direct electric current is called impedance, indicated by the letter Z. Resistance and reactance are two distinct scalar (one-dimensional) phenomena that combine to form impedance, a vector (two-dimensional) variable.

Z^{} = \frac{V}{I}

(for a pure resistor where Z=R,preserving the form of the DC Ohm's law).

I=\frac{V}{Z}

I = \frac{100}{5}

I = 20 A

Therefore, A circuit with an impedance of 5 ohms and a voltage of 100 volts has a current flow of 20 A.

Work out the current through an electric kettle with a power of 2.2 kW if it uses the 180 V mains supply. Round your answer to 2
weeeeeb [17]

Answer:

12 A

Explanation:

Given,

Power of electric kettle=2.2 kW=2200W (since 1kW=1000W)

Voltage=180V

Current=?

Power = Voltage*Current

Current = Power ÷ Voltage

=2200W ÷ 180V

=12.22 Ampere

=12 A
