Ohm's first law:
By Ohm's first law, the voltage is the multiplication of the current by the resistance, that is:
The voltage is measured in Volts, the current in amps and the resistance in ohms.

Then
The voltage is 10 + 2j volts.
Answer:
C=5h+3 when h=5
C=28
Step-by-step explanation:
She charges $5 per hour (5h)
