Question:

Solve the given problems. Refer to Example 4.

If I = 0.835 − 0.427j amperes and Z = 250 + 170j ohms, find the complex-number representation for E.


Data from Example 4

In an alternating-current circuit, the voltage E is given by E = IZ, where I is the current (in A) and Z is the impedance (inΩ). Each of these can be represented by complex numbers. Find the complex number representation for I if E = 4.20 − 3.00j volts and Z = 5.30 + 2.65j ohms.
Because I = E/Z , we have
