Question

7. ELECTRICITY In an AC circuit, the voltage E (in volts), current I (in amps),

Answer 1

The current in the circuit will be equal to (10 - 3j)/(4 + j) when the voltage is 10 - 3j and impedance is 4 + j.  

What is Electrical energy?

When put in an electromagnetic field, charged matter experiences a force due to the fundamental property of electric charge. Positive or negative electrical ions are possible.

When two charge are in opposition to one another, they repel one another. The term "neutral" refers to an object has no net charge.

As per the given information in the question,

Voltage, E = 10 - 3j

Impedance, Z = 4 + j

Then, the value of current will be,

E = IZ

I = E/Z

I = (10 - 3j)/(4 + j)
