Answer:
Step-by-step explanation:
Given
ET = 120 V
, R = 30 Ω,
XL = 40 Ω.
To find = IR=?
as in circuit inductor and resistor are parallel so ET =EL = ER = 120V
IR = current through resistor = IR = ER/ R
= 120V /30Ω.
= 4 ampere.
For number 1. it is wrong. It is fresh water. Ocean water is salt water. I don't know the rest, sorry. I will come back if I find out though! :D
Answer:
